Instant Runoff Voting: The Time Has Come
By Peter Drake of Portland, Oregon. Peter is an assistant professor of computer science at Lewis & Clark College.
The 2002 Oregon Governor's race and the 2000 US Presidential race both saw a minor failure of democracy. Each of these races saw the election of a candidate -- in one case a Democrat, in the other a Republican -- whom most voters voted against. Indeed, the winner was probably not even the second choice of most voters.
This situation can arise whenever there are more than two candidates. One solution is to hold run-offs. Once the weakest candidates are eliminated, the voters can make a final choice. Traditional runoffs, unfortunately, require time and money.
There is an even better solution: instant runoff voting (IRV). With IRV, voters aren't limited to only listing their favorite candidate. Instead, each voter lists a first choice, a second choice, et cetera. In the first counting of the ballots, only the first choices are counted. If any candidate has a majority (more than 50% of the votes), that candidate wins, as usual. This is likely to happen in most races.
If no candidate has a majority, an instant runoff is held. The candidate with the fewest first-choice votes is eliminated and those ballots are redistributed according to the second choices listed. It's just like a runoff, but there's no need to print and mail out new ballots. If there are more than three candidates, the instant runoffs continue until one candidate has a majority.
Because IRV requires a majority (rather than a mere plurality), it elects candidates that the electorate can get behind. IRV eliminates the "spoiler" problem, which benefits the major parties. IRV allows voters to safely vote for their favorite candidate (even if he or she is a longshot), which benefits third parties and independents. IRV encourages positive campaigning, because candidates want to be ranked highly on as many ballots as possible.
Sounds good? This year, we have a chance to make IRV happen right here in Oregon. House Bill 2638 would enable cities and counties to use IRV if they choose to do so. It doesn't cost the state anything and it doesn't force anyone to use IRV -- it just gives localities the option.
Oregon has a long tradition of political experiments, and HB 2638 would allow us to try out IRV in a few places before adopting it statewide. This is probably overcautious, as IRV is already well-tested. It's used to elect the mayors of San Francisco and London, the president of Ireland, representatives in Australia, and the president of the American Political Science Association.
Please contact your state legislators and encourage them to support HB 2638. Let's bring IRV to Oregon!

FYI, for at least the first election held under Portland's commission form of government (adopted in the early 1900s), the City used a form of instant runoff voting.

I would like to spread awareness of the Condorcet method. To voters, it appears the same as instant runoff voting, but Condorcet is much harder to vote "tactically" under (and there's less need to, too). The biggest problem with IRV is that "in some situations, if a voter or group of voters decides to rank a preferred candidate lower, it can result in that candidate winning the election, whereas if they had ranked the candidate higher, according to their sincere preference, that candidate would not have won."
There are tradeoffs in every election system, but I believe the tradeoffs are lower using the Condorcet method. Determining a winner is more complicated than in IRV, but it's still an algorithm that can be coded into law fairly easily.
Thus ends my attempt at raising awareness. Thanks for reading!

Instant runoffs make the assumption that more than 50% of the electorate must vote for a candidate in order for their representation to be legitimate. Although the republic has operated effectively without this requirement, let's say that we make that assumption. Let's say there are 5 candidates (though Australia, which uses IRV, typically has far more candidates for any given seat). Each voter ranks their candidates 1 through 5. At the tally, if no candidate reaches the 50% mark, then the candidate who is tallied at 5th is dropped. Those ballots that had ranked the 5th tallied candidate 1st are reexamined, and their votes are redistributed to their 2nd ranked candidate. And on down the line until somebody reaches the 50% mark.
This creates two big problems.
First, voters are denied the right to reevaluate candidates in the context of a campaign - they are no longer allowed to change their mind. The assumption is that when there are 5 candidates, you would rank the same person 1st as when there are 2 candidates, but, if you were given the opportunity to reevaluate those 2 candidates, then you might change your mind.
The second big problem is that some voters are allowed to vote twice - once to decide who stays on or drops off the ballot, and again when their votes are redistributed to their 2nd (or 3rd or 4th) ranked candidate. This runs contrary to the "one person, one vote" principle of our constitution. It also means that, in practice, majority party voters get one vote while minority party voters get two votes – because majority voters vote for the majority candidate which generally stays on the ballot, while minority voters get to "vote their conscience" once for a candidate that will drop off the ballot and then again for a candidate that will stay on the ballot.
There are also several issues that arise in how to work the tally when voters fail to rank a 2nd place candidate but rank a 4th and 5th, or when voters vote only for a first place candidate and fail to rank any other places. Yes, this happens. Often.
The point of all this is that instant runoff voting is not nearly as simple or easy to implement as it may seem at first blush, and it has the effect of compromising voter autonomy. For more fun with IRV, check out this guy from Utah.

Yes, there are a number of other voting techniques, including approval voting and the Borda count. Arrow's Theorem tells us that none of them are perfect -- it's possible, for any of them, to come up with weird situations where something undesirable happens.
I don't want to get into an argument over whether IRV is the best choice, but I think we can all agree that plurality voting is pretty much the worst choice. Since there's an actual bill in the legislature that would enable (not mandate!) IRV, I'm on the bandwagon.
Mar 17, '05
Curiously, Anne's comment above is exactly the response I got from the Secretary of State's office. My reply is below
Regarding voters changing their minds:
There's always the possibility of new information coming along. Any voting system asks voters to commit on election day, even though some scandal might come out in the next day's paper.
Are you proposing that the voters might want to take into account how others voted in previous rounds? I believe this would be a bad thing, as it leads to insincere "strategic" voting.
For example, suppose there are four candidates, A, B, C, and D, and I prefer them in that order. On a first round of regular voting, the results are:
A 36% B 25% C 25% D 14%
There is no majority, so D is eliminated and there is a second round of voting among the remaining candidates. Even though A is still my favorite, I would be wise to vote for B to make sure that C is eliminated. This is a dishonest vote. Instant Runoff Voting effectively eliminates this sort of abuse.
Regarding "voting twice":
This is a misinterpretation. Every vote is counted exactly once in every round. Suppose, for example, that you vote for a major party candidate and I vote for a third party candidate. In the first round of IRV, my candidate is eliminated. My one ballot is moved to one of the other piles. In the second round, my vote is counted for that candidate AND your vote is counted again. One person, one ballot, one vote per round.
One might more reasonably argue that the standard plurality voting scheme violates the principle of "majority rules" because a candidate can win with a plurality even if a majority of the voters think that candidate is the worst one.
Regarding undervotes:
These are non-issues. If a ballot doesn't have a 2nd choice listed, go on to 3rd, 4th, and so on, until a vote is found. If no votes are found, discard the ballot; this is just like an "undervote" in traditional voting systems.

Since there's an actual bill in the legislature that would enable (not mandate!) IRV, I'm on the bandwagon.
Wait, when did it become dis-enabled under Oregon law?

The second big problem is that some voters are allowed to vote twice - once to decide who stays on or drops off the ballot, and again when their votes are redistributed to their 2nd (or 3rd or 4th) ranked candidate.
This is a perspective issue, not a reality issue. The other perspective is that normal runoffs suffer from the same problem -- people vote once to decide who stays on the ballot, and then again to decide the winner.
As for the enabling of IRV, when did Article II, section 16, of the Oregon Constitution become null and avoid? It says, in part:

Or are there specific statutes which defined as elections as not including IRV, which this HB then changes?

I should have thrown all of these into on comment, but I keep thinking of something else after I'm done.
Here's my one big reason for tending to support IRV: It packs more data into each ballot. The off-shoot result of allowing people to rank candidates in this manner is that it communicates more clearly the desires of each voter on a single ballot. It will mean something of note and import to the end-result of the winning candidate couldn't get past the threshold until the second or third go-round -- it tells both the candidate and the populace more about the electorate's views than does a simple one-round plruarlity-wins ballot.

Unfortunately, Condorcet voting has its flaws as well. Number one, for someone like myself who didn't want to support John Kerry because he voted for the invasion of Iraq, voted for the PATRIOT Act, and voted for the North American Free Trade Agreement, I would not want my vote to count to help elect John Kerry unless all of my other choices, Nader, Cobb, and Badnarik, had been eliminated. Condorcet helps to elect your second and third choice vote, whereas Instant Runoff Voting (IRV) only allows support for your highest-ranked candidate who has a chance to win. Borda does this as well, which is why i don't like Borda, personally. I want my vote to count in rounds amongst my preferences, not for all the candidates i ranked.
With IRV, your vote only counts towards candidates who can possibly attain a majority. Condorcet is superior in its mathematical application, but it is terribly confusing and very difficult to explain in 5 minutes to someone highly educated.
Anne posted that counting for different people at different times violates the Supreme Court of the United States' standard of "one person, one vote." This is NOT accurate at all, as for one, your vote is ONLY counting for one candidate at one time, not to mention her interpretation of that standard. The standard was actually meant to state that each person must have an equal vote and equal power. IRV held up under court challenge in Michigan, the case and judgement are available here: http://www.fairvote.org/library/statutes/legal/irvlegal.rtf . Since there is case law clearly conflicting with Anne's statements, I think we can determine that point is not valid.
Second point Anne raises is that voters who rank candidates who end up with more votes don't get their vote counted for second choices because their candidate is not eliminated. That is the point: that is their highest preference, so i am not clear why they would want their second choice counted. All who have theirs counted did not want the candidate it would be counted for more as they would have ranked their candidate higher. This seems a pretty invalid argument against IRV, to be honest.
The third point Anne raises is that ballots that have their candidates eliminated and the votes are exhausted cause a problem in determining a majority. This is also not accurate as they are considered "exhausted" and removed from the total. A majority is still determined as they don't count anymore in the further rounds of counting since the voter has indicated no preference of the remainders, or rather has indicated to prefer that none of the remainders are elected, in actuality, by not voting for any of them. The voter has every right to do so.
Finally, I agree all methods, including approval voting, my LEAST FAVORED of all the alternatives, are preferable to pluralities. I like IRV and Condorcet the best, though i really think Condorcet is too complex to every implement. And Borda presents situations where someone that doesn't have a majority or even much of first choice votes could win. Electing someone with less than say 10% of the first choice votes would cause a horrible outcry by the losers that I don't think Borda would survive. Borda would be blamed for the loser losing and we would lose our precious reform.

Here are my concerns about instant runoff voting 1) The 2002 Gov. campaign was mentioned. What if someone thought of Tom Cox and Kevin Mannix as anti-tax blowhards who hadn't proposed any specific solutions? This idea implies that Cox, Mannix, Kulongoski (or Nader, Gore, Bush in 2000) were of equal quality and that one or more candidates hadn't said something that offended any voters. What if they weren't equal in the eyes of voters?
2) Any political argument quoting a theorem bothers me. Has the person quoting the theorem gone door to door for a candidate? Can this person imagine going door to door explaining this system, esp. to people so busy with work and family that if you came to their door they'd say "you've got 90 seconds--what do you want?".
3) I was once involved in an organizational election with this kind of a system. I was going to vote for the 3rd candidate as my first choice, until I discovered this person was making a side deal with one of the more well known candidates. I suspect there are lots of ways to "game" the system.
I don't see how this helps.

I suspect there are lots of ways to "game" the system.
In of itself, this is irrelevant, because there are many ways to game any system. The question is whether or not in the aggregate, the benefits of any given system outweigh the risks.
As to the issue of going around explaining to people who IRV works, the answer is rather simple: Any jurisdiction which institutes IRV should pick a start-date far enough into the future to allow public education for quite some time before there's ever an IRV election held.

The One True b!X points out that instant runoff voting (IRV) is allowed by Article II, Section 16 of the Oregon constitution. Unfortunately, it’s possible to interpret that section and various laws in such a way as to prohibit local jurisdictions from using IRV. I’m not saying that’s the right interpretation, just that it’s an interpretation some people make. This leads to election officials making black-and-white pronouncements like the following:
“Oregon law provides that ‘the person receiving the highest number of votes shall be nominated or elected.’ (ORS 254.065) Statutes would have to be amended to provide for Instant Runoff Elections in Oregon.”
The above quote is from written testimony Kaufmann submitted to the Multnomah County Charter Review Committee on 4/13/04 when it was considering whether IRV should be used for county elections. It should come as no surprise that the committee dropped the subject: The director of elections told them they couldn’t do anything, and they believed him. It doesn’t matter whether he was right or not.
Note especially that he didn’t say the matter was inconclusive or subject to interpretation. He presented one interpretation, and he presented it as absolute fact.
Something along the same lines happened when Eugene was considering IRV in 2001. The prospect of an expensive court battle with the state elections division siphoned important energy from the effort to educate people about IRV.
The bottom line is that while it might be possible to implement IRV in Oregon without first changing state law, the process of doing so would be (already has been) like banging our heads against a brick wall. If we can pass a state law that explicitly allows local jurisdictions to use IRV, that will help everyone focus on the real question: whether IRV is better than what we’re using now.

Thanks, Peter, for pointing out HB 2638. This bill has the potential to do wonderful things for our state — voter turnout tends to increase significantly following the adoption of instant runoff voting, and remain elevated. That alone should be sufficient reason to support this legislation.
That said, I want to put in a plug for the Borda Count — and in particular, Instant Runoff Borda Count. Borda Count elections give each candidate a point for every other candidate over whom he or she is preferred, and require every candidate to be ranked. In simple Borda, the candidate with the most points wins. In instant-runoff Borda, the candidate with the least points is removed from the ballots and the votes are re-tallied. For some fairly complex mathematical reasons (see Donald Saari's books, referenced in the bibliography of my thesis), Borda Count turns out to be the least paradoxical voting system we've thought of yet.
Can it be implemented? Yes. That question was the subject of my thesis.

Article II, Section 16 of the Constitution remains in place, and ORS 254.065 does in fact say what John Kauffman says it says (the person receiving the highest number of votes shall be elected). The upshot is that IRV would require statutory authority and some statutory changes to implement. So there's that.
And since Peter's post was exactly the same as the email he sent to the SOS office, I thought it appropriate to post the email that the SOS office sent back to him.
Moving on...
IRV has become a darling of minority party people on all sides, because it allows them to "vote their conscience" for an unelectable candidate without having to suffer the consequences of being a spoiler. They then also get to have a dispropotionate amount of power over both majority party people and over who gets elected, allowing the minority to gerryrig the election as they see fit, and I'm sure they're very excited by this prospect.
As for the "one person, one vote" principle, it's not a problem of perspective, it's a problem of equal protection under the constitution. IRV failed in Alaska in part because none of the IRV proponents could give a satisfactory answer to why minority party people should get more than one vote while majority party people get only one. The "one vote per round" argument is disingenuous, because there is only one ballot, and on that one ballot the majority party voters' votes count once, and the minority party voters' votes count more than once. That doesn't sound like "one person, one vote" to me.

Because it always elects the candidate exactly in the middle of all voting, Preferential (ranked) Ballot [PB] is top-dead-center-counter-extremist & thus more anti-terrorist than all the many recent retrenchments combined. While Preferentiality would be equally useful for all else its real power is most clearly shown in the case of the impending civil war in Iraq. Unless the Iraqi Parliament comes to select its PM by PB, it may not hold, & the world will be in danger of going to war over some oil well. Because it gives the Iraqi minorities a real say in which Shia gets chosen, PB is the only thing that will encourage them to support any plan more than perfectly inadequate confederation. Because it gives all combinations of programs, & not just parties, an equal chance of winning it is the only thing that is really just, for Iraqis & everyone else. Because it will always provide a market-based alternative to all proposals for justice offered by the left & vice versa, it is something that both sides could & should support. Be a light to the world & help put this powerful idea in time to as many as possible. We imagine running on the SINGLE ISSUE of Preferential Ballot & allowing a citizens advisory board based on “Organized Communications” to guide our vote for the rest. Everyone should be sure to do the same, from the most local on up. $15,000.00 will get a full page add in USA Today, which could be enough to put it to everyone. Organized Communications is small randomly assigned discussion groups electing reps to higher & higher levels by means of Preferential Ballot until one small group at the top necessarily names the next winner of the next election, thereby installing preferentiality virtually instantly, & inevitably globally, no matter what ladders are pulled up next.
The “additive” (as opposed to the more skewed, & more widely espoused, “eliminative”) form of Preferential Ballot is the ranking of all candidates by each voter. The first choices are counted & if noone has 50% then the next choices are added in, & so on, until someone finally does. It is the sole unchangeable plank & bylaw of the Preferential Ballot Party, the only practicable third party, whose self-organizing principle is Organized Communications. Please see www.preferentialballotparty.org. How can we ask it of others if we do not have it ourselves?

Oh, and Anthony, (IRV held up under court challenge in Michigan) one state's trial court does not a constitutional case make.

Replying to Anne:
I believe IRV is good for major parties, minor parties, and the voters. As I said in my original piece, we've seen two major elections lately where the candidate that was least liked by a majority of the voters won. That's not good democracy.
The argument from Dana Dickson (the Utah link above) that "will announce who he supports to his supporters and they will vote accordingly for that candidate to be the #2 choice on their IRV ballots" is a gross overestimate of how organized and disciplined third parties are.
This site, which likes Condorcet voting, argues that IRV is actually BAD for third parties:
http://electionmethods.org/IRVproblems.htm
(I'm not sure I agree with that site, but there it is.)
I hate to get into an "is too, is not" debate over one person, one vote, but the statement that the major party votes only count once is simply false. Please have a look at this simple example:
http://www.pacificgreens.org/issues/irv.shtml
In the runoff, the votes for the minor candidate (Bob) are indeed counted again. However, the votes for Akiko and Carlos are also counted again. Every vote is counted the same number of times.
As a final comment on "gaming the system," one must imagine that nobody would know how to do this better than political scientists. The American Political Science Association uses IRV.
(The 32,000-member Mathematical Association of America and several similar organizations use approval voting, but that's not on the table in Oregon this year.)
Mar 18, '05
Incidentally, what would really give third parties power is proportional representation: if your party gets 5% of the vote, you get 5% of the seats in the legislature, even if you didn't win in any particular district. Again, no bill this year, so it's not an issue.
Mar 18, '05
Anne: Yes, of course Kaufmann’s quote was correct. That wasn’t my point. My point was that he presented as fact one interpretation of what his office could legally do, when there is at least one other well-known and very defensible interpretation.
The Oregon constitution says IRV may be enacted “by law”, and there is judicial precedent that local ordinances are “laws”. Therefore, the constitution can be interpreted as giving local jurisdictions the right to enact IRV should they choose to do so. Under such an interpretation, it really doesn’t matter whether ORS 254.065 allows IRV or not, because state laws are subordinate to the state constitution.
So your claim that “IRV would require statutory authority and some statutory changes to implement” is by no means a foregone conclusion.
It would still be good to pass a state law that explicitly allows local jurisdictions to use IRV, because that would clarify the situation.
10:56 a.m.
Mar 18, '05
Fillard,
There is an order to "law" - city ordinances fall below state statutes and state statutes fall below the constitution (as you note). However, many (most) constitutional provisions require state statutes to implement. So yes, it does matter whether the ORS's allow for IRV, and although IRV is permitted by the Constitution, it is not required and cannot be implemented unless and until there is some direction in ORS. Hence HB 2638, with brand new language and amendments to 8 provisions of ORS.
11:38 a.m.
Mar 18, '05
Regarding all complaints that this or that election system is problematic, I highly recommend reading Donald G Saari's book, "Chaotic Elections" (or, for the more mathematically inclined, his "Basic Geometry of Voting"). Erica Klarreich summarizes nicely:
Regarding choice of voting systems for secret-ballot elections, my preference ranking is approximately as follows: modified Borda STV > modified Borda IRV > Borda STV > Borda IRV > STV > IRV > Condorcet > Approval > just about anything else > Plurality. (There are two modifications I would make to Borda, primarily because it can be unwieldy to rank all preferences. The first would be to simply require pairwise comparison of all candidates, allowing for intransitivity and neutrality, giving one point to the winner of each comparison. The second would be to allow / require ranking of a limited number of candidates.)
What I think would be truly ideal would be STV primaries followed by an IRV Borda general election (STV general for multi-seat races elected from the same district).
No voting system is perfect for democracy, but IRV is good for democracy, and far better than what we have now. I support IRV.
We have always stood for democracy, and I pray that we always will.
12:17 p.m.
Mar 18, '05
Therefore, the constitution can be interpreted as giving local jurisdictions the right to enact IRV should they choose to do so. Under such an interpretation, it really doesn’t matter whether ORS 254.065 allows IRV or not, because state laws are subordinate to the state constitution.
I'm rushing here, so I don't have the Oregon Constitution open again, but I thought that what the relevant portion said was that IRV was allowed unless a state law is passed saying otherwise -- meaning the constitutional provision in question grants the legislature the right to disable IRV authority statutorily. In which case, current statutory matters such as that referenced by Kauffman in fact would be the binding law on the issue.
As for the "one person, one vote" matter, I still think it's perspective. The "vote" of each person can be seen either as the final outcome of the IRV balloting process, or as each individual go-round within an IRV ballot. There's nothing to say its one or the other except how we perceive it.
Mar 18, '05
Can't we just give each voter 10 colored dots for them to distribute as they like next to candidate names on butcher paper that we hang up around town?
2:57 p.m.
Mar 18, '05
I think part of what's at stake here is the power of parties to drive the process. Reading through the thread, I reacted to what seems to be a stats-fueled argument. I recognized with Gavin's quote above what it was: systems yield different results. Given that we don't have a parliamentary system, we're stuck with elections that will not be proportional. The question then is: to whom do we give the power in the situation.
Currently we give it to the parties. I think IRV would dramatically weaken the parties to control the system. As someone who's voted for many non-party candidates, I'm sympathetic to that impulse. But over the past few years, I've also begun to see the damage third parties can wreak on American politics. By removing themselves from the coalition-building process, third-parties often represent litmus-test, single-issue candidates. This has the obvious effect of further polarizing politics because after the election, it's the parties who have to try to do the business of governing.
It's possible that IRV would so weaken the parties that it would force a realignment of politics, but I don't see that happening for years or decades, if at all. I wouldn't really advocate on either side of this issue (campaign finance and media-access reforms are the ways to affect real change), but I think folks are missing what's really at stake and what the consequences would be.
(On the other hand, Blue Oregon should win some kind of media award for this thread, which is amazing in its richness of information, clarity of argument, and all around graciousness of commenters.)

The problem with it is that it is highly subject to strategic manipulation. Those with better access to polling data can figure out the likely distribution of votes, and bullet vote for their favorite among the candidates who, given the known preferences of the general voting population, the manipulators can elect.
The "ten colored dots" approach (whose technical name I'm not remembering offhand) is in the extremely small group of voting systems that are worse than plurality voting, in terms of the freqency of paradoxical outcomes.
Mar 18, '05
Lest we forget, not every election has more than 2 candidates. People who vote 3rd party sometimes control the outcome (Smith over Bruggere, 1996, Riley vs. Gallegos and Burley vs. Stiegler in 2004, for example) but in many cases there are only 2 people running. There is a 33 majority in the House. 7 of those races were decided by less than 1000 votes. I don't see how IRV would change that and maybe more energy should be given to winning the narrow 2 candidate races.
BTW, did you know that freshman Betty Komp won by a larger margin than Speaker Minnis? Both of those were 2 candidate elections.
Election returns are fact (unless of course someone tampered with the vote count). IRV remains a theory, it seems to me. And why would ballot security be stronger in IRV than currently in Oregon?

I'm pretty sure that was the voting method used at the Engage Oregon conference to determine the Bus Project's policy priorities.... right?
And, incidentally, I'm pretty sure that's actually another kind of voting - maybe called preference voting? I recall Lani Guinier pointing out that it's a form of voting in city council elections in the South. You get X number of votes to distribute in any way you see fir over Y candidates. It tends to empower voting blocs that don't have a majority of the vote - they can "bullet vote" all their votes on one candidate, virtually assuring election in a multi-candidate field.
Great thread here, folks.

It's interesting to me that there seems to be overwhelming third party support for IRV (unscientifically judging from this thread and conversations with green party folks)- because "spoiling" an election is a tactic that third parties from both the left and the right use at times to punish major parties when they are perceived from straying too far from their core values.
For example:
In 2000, Nader argued at times that the election of Bush might be a good thing for the environment, among other things, because he would be a "provocateur," not an "anesthetizer" like the Dems. Enviro groups would increase their membership, campuses would be energized, ect...
In 2002, many libertarians used their "incumbent killer" strategy- specifically fielding candidates in key races- with the stated goal of draining votes from Republicans who voted for tax increases ect..
I'm still somewhat agnostics of the merits of IRV, but I really applaud the idea implicit in the proposal that elections are ultimately about governing, not solely making a statement or "sending a message."
It seems like third parties would be trading away one of their main tools to hold major parties accountable in exchange for the chance for a greater mandate on their party's issues and ideas (and are assuming this would open the flood gates of more people "voting their conscience").

Actually, I guess that green party folks or libertarians could try to convince their supporters in extreme circumstances not to pick the D or R as a second choice, but this seems like it would be a fairly difficult- and self-damaging- reque3st to make.

As a third party member, I don't see the spoiler possibility as a useful tool. While it may be possible to play kingmaker in a well-disciplined congress or parliament, nobody is in a position to offer the votes of an American political party in return for some policy promise. Many third parties wouldn't trust a major party to keep such a promise.
More to the point, we don't like being thought of as spoilers. We have issues we'd like to talk about, but the media won't talk about anything but spoiling. In 2000, Nader couldn't get a word in edgewise without a TV host asking him, "But aren't you worried about taking votes away from Gore?"
Now, for added information, here's the site plugging approval voting:

Interestingly, Arrow's Theorem doesn't apply to approval voting, because it's not a ranked-ballot system.

Sorry Peter, Arrow does apply to Approval voting - it is a ranked ballot in which all candidates above a certain threshold are given a point, and all others are not.

Peter,
Your argument seems to rest on two flawed claims.
First, what do you mean when you write this: The 2002 Oregon Governor's race and the 2000 US Presidential race both saw a minor failure of democracy. Each of these races saw the election of a candidate -- in one case a Democrat, in the other a Republican -- whom most voters voted against. Indeed, the winner was probably not even the second choice of most voters.
Are you claiming that neither Bush nor Kulongoski were the Condorcet winners? That is a false claim at least for Bush/Kerry. The outcome of the plurality system in this case was, in all likelihood (almost assurently based on survey data in the US Presidential case) the same as would have resulted from IRV.
Second, you indicate that Oregon should adopt IRV because we have a "long tradition of political experiments".
Are you arguing that we should experiment simply for the purpose of experimenting? In my opinion, reform for the purpose of reform has gotten this state into some serious problems.
If you have a problem that you think IRV would cure, then OK. But reform for reform's sake alone leaves me cold.

Paul, he didn't mention the 2004 election. Bush/Kerry's not at question here. As you quoted him, he was talking about 2000 (Bush/Gore) and the '02 gubernatorial.
Mar 19, '05
Coming late to this discussion, I will say only that I find the all the objections to IRV unconvincing. I am a Democrat.

Gavin: you may be right. On which of Arrow's criteria does approval voting fail?
Here's a nice page that includes (about a third of the way down) the Big Table we've probably all been looking for:

Peter: I believe Approval Voting fails the independance of irrelevant alternatives ("IIA") test in the following way:
Suppose ten people like candidates K > N > B, one person likes N > K > B, and ten people like B > K > N. If the ten for K also give points to N, and the ten who like B give points to no-one else, then the outcome depends on whether the one person who likes N gives a point to K or not. Thus, while no-one changes the ordering of their preferences, they do change the cardinality of their preferences (indicated by the choice of cut-off for granting points), and the outcome is changed.
Because it fails <abbr title="independance of irrelevant alternatives">IIA</abbr>, it does not provide a counter-example to Arrow's Theorem. (No big surprise — we'd all have heard a lot more about it if it disproved Arrow.)
Mar 20, '05
Gavin:
Thanks for the example.
First off, I of course don't mean to say that approval voting disproves Arrow's Theorem. A theorem is a theorem, after all -- once it's proven, there's no going back. However, if the theorem is of the form, "If a voting system is a ranked voting system, then it can't meet all of the following criteria," then a non-ranked voting system might still meet all of the criteria. Approval voting proponents seem to claim that this renders the theorem irrelevant to approval voting. I should look into the precise definition of the theorem more closely (and consult a colleague who has more expertise on this stuff) before making this claim.
Moving on to your example, I don't believe this is a violation of IIA. The outcome hinges on whether the last voter approves K. K is one of the contenders, so not irrelevant. If the outcome between K and B depended on whether someone approved N, that would be a violation of this criterion.
Your example does raise a legitimate complaint, though: under approval voting, voters must decide where to draw the cutoff line among their preferences, and it may matter. I believe approval voting is strategy-proof provided that everyone's preferences are dichotomous, i.e., each voter thinks, "I find this set of candidates acceptable, this set unacceptable, and beyond that I don't care."
Returning to the origin of the thread, I'll reiterate: almost anything is better than plurality voting, and IRV is the reform we have a shot at this year.

Peter,
Don't worry -- there is no voting system other than pairwise (Condorcet) that does not violate Arrow. Arrow is your ally in this debate (as you note here: Returning to the origin of the thread, I'll reiterate: almost anything is better than plurality voting, and IRV is the reform we have a shot at this year).
The issue with Arrow is always this: which of the various criteria are you willing to violate and how much?
IRV provides a better translation of individual preference orderings into social preference orderings than does plurality voting.
My apologies for misunderstanding the election examples, although let's note that in the 2000 presidential election, it was the electoral college, not plurality voting, that resulted in a Bush victory.

While this is technically true on initial examination, it may not be true in the final analysis. All of this is speculation, of course, because we don't have ballots with full preference rankings, but it is believed by many people that the electoral college votes would have been distributed differently under IRV than they were with plurality. What is unclear is whether enough Buchanan supporters would have ranked Bush second to outnumber the Nader > Gore votes (and so on).

It seems to me that Anne is really grasping at straws in trying to make a case that IRV somehow gives some voters more votes than others: "..there is only one ballot, and on that one ballot the majority party voters' votes count once, and the minority party voters' votes count more than once." That is plainly not true. On that one ballot, each voters' vote counts once in each round, the same as if there were multiple rounds of runoff voting separated by time. If I vote for the third place finisher in the May election for Portland City Council, does that mean I can't vote in the fall runoff election between the top two candidates because my vote in this election has already been counted once in the first round? Assuming that most of the people who voted for the top two candidates will stay with their candidate in the fall election, it is indeed the voters who did not vote for either of them the first time around who will determine the outcome in the fall election. So instant runoff voting doesn't give any more power to those who vote for third and fourth place finishers than regular runoff voting does. But perhaps Anne is opposed to all kinds of runoff elections, or any elections that require a majority instead of a plurality.
Jeff Alworth worries about weakening the major parties and giving rise to a proliferation of small parties focused on single issues who withdraw from the coalition building process. One of the problems with the major parties is that they don't really have consistent philosophies or ideologies - they are big tent coalitions rather than true political parties. They don't adequately represent the diversity of views accross the country. I think IRV would actually facilitate coalition building while allowing the development of more diverse and innovative parties, while at the same time maintaining the stability the current two-coalition system offers by elminating the spoiler phenomenon.
IRV would facilitate positive campaigns because all candidates would have an incentive to rank high on all voters ballots, rather than the current system which encourages candidates campaign to increase the negative perception of their opponents so as to depress turnout among their oponents' voters.

Adam is correct. Everyone's vote counts the same in each round. The confusion stems from how the votes are reallocated -- if you rank ordered Party A first and that is one of the top two parties, then your vote for A is not reallocated. It is still "counted" in the second round, it is just that your rank ordering does not change.
For instance:
First round, A gets 3 votes, B gets 3 votes, C gets one vote. Eliminate C and reallocate.
In the instant runoff, A gets 3 votes from voters 1-3; B gets three votes from voters 4-6.
It is only for V7 that that the elimination of C changes the most preferred party to B.
B defeats A 4 votes to 3.

It's fun seeing so many Reedies contributing to this thread. (First Gavin, then Paul, and now myself) I have to say, I find Anne's comments about one person one vote rather surprising. The truth about any social choice (and that’s really what all voting is) is that it is a contest between n+1 options for n winners. When I am choosing who I want for president, I know that in the end there will be someone who comes in first, second, third, and so on. Under a plurality voting system, I either make the choice to vote for one of the two individuals I predict will come in first or second, or I make the choice to vote for someone I do not expect to have a chance at winning. In a race for one seat, the only choice that matters for any given voter is the choice between the first place and second place candidate.
The fundamental concept which I think Anne misses is that any votes for candidates other than the winners do not matter. In a gubernatorial election, unlike in horseshoes, close doesn’t count. Thus, under the current system, we force voters to make a choice between voting for the person they prefer, and voting strategically in order to ensure their most favored outcome. Forcing voters to misrepresent their preferences in order to get the outcome they desire is bad for democracy, because it results in a misrepresentation of what voters actually desire.
What it demonstrates is that the election system used is not accurately allowing voters to both have their voice matter, and honestly express what they think. Anne believes like if you want your voice to matter, you should have to pick one of the two major parties, because such system allows the two major parties to retain control over the elections. I believe that the two major parties should have control if and only if the voters actually agree most with what they say. A majority of likely voters right now would vote for the democrat in a congressional election (according to the last issue of polling report I looked at). Yet, we have a Republican congress. This is due largely to the fact that we have districts, but also partly due to the fact that some voters cannot express their true preferences on the ballot and at the same time have a say in the outcome.
I think the reason Democrats fear IRV is simply numbers. Anne obviously has ties to the Secretary of State’s office, who I’ve found out from others has many high ranking officials opposed to IRV (though I’m not sure about preference voting generally). The fact is, in Oregon, the Libertarians outnumber the Pacific Greens, and because, if you look at the last State House and Senate elections, there were many more Libertarian candidates than Pacific Green candidates, the Democrats were able to garner more third party support from green voters than the republicans were from libertarian voters. It is partisan politics at its worst, however, to oppose a better election method simply because it helps you get elected. I’m a Democrat, and I want Democrats to be in power because they’re making schools better and helping working people, and taking care of the environment a lot better than the republicans are.
But beyond being a Democrat, I am a democrat (small d), and that means I support democracy, for better or worse. Just like we should build the best possible schools so everyone can get a college education and everyone’s lives can be better, we should have a voting system where everyone can be honest about their preferences and everyone can have their opinion matter. Plurality voting does not do that. Probably one of the worst arguments I have heard attributed to members of the secretary of state’s office is that we should oppose IRV because voters are too stupid to rank their choices. I’ve run the elections at Reed College for two semesters so far, (I’m a sophomore) and I just changed our system of electing our Senate from a plurality system to a preferential system (STV). Instead of Reed students having to vote for five candidates because there are five seats open, students now get to rank their preferences, and can give multiple individuals the same ranking.
While I’m sure some people will screw this up, people screwed up when they had to check off five people, instead checking off four or six (and in the latter case having their ballot thrown out). And while I’m sure some people wont understand the method by which the votes are counted, the important thing is that they are counted, and are counted fairly. The nice thing about STV is that it that it is particularly resistant to strategic voting, and so for the first time, Reed elections will actually be an expression of what the voters actually think, rather than what they are forced to mark in order to get their most favored outcome.
I think this serves as a good analogy to Oregon. IRV is not the perfect system (Condorcet is, but it doesn’t always produce a winner, however, there are modifications of Condorcet like Ranked Pairs which fix this), but IRV is at least fairly explainable to people, and it suffers from the same failings that an actual runoff election would have. (In a plurality runoff election, I can vote for the person who I think will be a weaker challenger to my favorite candidate (say, voting in the Republican Primary for Mannix in 2002, rather than Kulongoski in the Democratic primary) because I think Mannix will have a harder time beating Kulongoski.) In both IRV and the runoff example I just described, I am taking a risk by not voting for or ranking highest my most favored candidate, and it is a risk I should not have to take. IRV does not give voters the ability to vote twice anymore than a runoff or primary system gives third party voters the ability to vote twice, once for the third party candidate in the primary, and once for the republican or democratic candidate in the general.
In the last Reed election, we had 7 candidates for Student Body President. Around 615 votes were cast, and after counting first preferences, the first place candidate only had 33% of the vote. We could have just left it there, called him the winner by plurality, and called it a night. But instead, all the voters who didn’t vote for him or the person who came in second got the opportunity to help make a choice which mattered, just like the people who voted for the first and second place candidates did. And this is what Anne misses. We aren’t giving third party voters two votes, we’re just giving them one vote. A vote which up till this point, they haven’t had. In the end, the person who got the most first preferences ended up winning the election, but only by 15 votes. And because we had IRV, a majority of people ended up actually deciding the election, rather than just 33%.

If our traditional 2-party system and plurality voting worked, why do we have over 30% independent/third party registrants and over 40% (most of the time) not voting?? Let's face it...our democracy is broken and needs to be fixed. We could start by junking party primaries that disenfranchise the +30% (and over 50% of people under age 35, as Phil Keisling likes to point out) but IRV is even better and should be encouraged. We should have PR, but America ain't a parliamentary system, but while we're at election reform, anybody for a unicameral legislature (one house) like Nebraska's?
Oh, and Kari...I recall that dot system at Hood River didn't work so well. The "ruling body" of the Bus decided to overturn its own convention bylaws and ultimately did not take on-board a couple of the "top 10" issues as determined by the attendees. Rule by executive fiat is definitely the worst system of all...so excuse me if I'm biased against the "colored dot" solution!

Yep. We have a two party system. Now quit your whining and quit trying to let yourself be a spoiler without suffering consequences, and play under the rules like the rest of us.
I, as a big D Democrat, do not fear IRV, I just think it's a bad idea. And I think that if you took an honest look at how it really works, particularly in the places that have implemented it and then thought better of that decision after experience, you would think it's a bad idea too.

I think the reason so many people are disillusioned by the "two party system" is that they feel disenfrancised by the coalition building process that is forced to take place before elections reather than after elections.
It is very easy in our current system for the major parties to pay lip service to some coalition members, make promises, and then do nothing after the election. Both parties make all kinds of promises during the election, then forget them after the election. Campaigns tend to be about anything and everything besides what actually gets addressed while Congress or the state legislature is in session.
If we had a different system that allowed people to vote according to their real beliefs, and then forced the elected officials to form coalitions after the election rather than before it, then we would see them having to actually make deals and compromises on the issues voters cared about, rather than just ignoring them completely because they perceive some issue isn't important enough or isn't their thing, or they figure they can talk and spin their way around it.

Everyone else: Please send your comments to your state legislator and your newspaper editor. The number of people reading this thread is dwindling as it gets longer.

Oh, beaut, let's look at Australia's success. Yeah, 75 years later and they're still spreading vegemite on their crumpets and playing cricket and eating kangaroo meat. Crikey, if Australia is what we would look like if we have IRV, they can keep it, mate.

Wow, I had been really appreciating how civil this thread had been, and then my friends started calling each other names. (And calling me names, but I'm not taking it personally.)
Really, we're all in this for the same thing — to hold the government accountable to progressive values. We might disagree about how to do that, but we agree on the goal (trolls aside). Clearly, some think that the current voting system already expresses our progressive values, and some think otherwise. (Correct me if I'm wrong.)
I happen to be in the latter camp, and I could go on at length about why, but I'm really quite curious about other perspectives on our current systems. What about our current system is better at expressing our progressive values than IRV? What concerns are there about IRV?
(Just to be clear, I don't think the "one vote per voter" vs "one vote per round" argument is going anywhere. I think we can safely set that one aside, and come back to it if we run out of interesting things to talk about.)
