[EM] Pirate Party of Sweden adopts the Schulze method
Hallo, in October 2009, the Pirate Party of Sweden adopted the Schulze method. See e.g.: http://forum.piratpartiet.se/FindPost174988.aspx http://forum.piratpartiet.se/FindPost176567.aspx http://forum.piratpartiet.se/FindPost191479.aspx The Schulze method is used in the internal elections (14 December 2009 to 17 January 2010) to fill the 82 list places for the upcoming Riksdag elections. There are 230 candidates and about 50,000 eligible voters: http://www.piratpartiet.se/primarvalskandidater Markus Schulze Election-Methods mailing list - see http://electorama.com/em for list info
Re: [EM] just to let you know ...
plurality leader in the initial tally ended up losing weak Condorcet compromise in third place if Burlington had used Condorcet rules ... there would be even more vociferous calls for repeal These are all semi-valid concerns in a country that is so used to plurality winners and single-party governments (winner without lots of / sufficient amount of of first preference support could be a weak single-party ruler). I note that also the spoiler effect is a quite well known problem in the USA and that the 33% plurality winner would have lost also with the old rules (the probability of electing a Republican might be bigger with the old rules though). All this together shows that the discussion and decision making is probably more abut who makes the best and most convincing claims at correct times than about who makes the correct and rational claims. There is no one making a rational summary of all the arguments. The discussion is more likely to hover around various simple claims (that may well be oversimplified, false, unclear, intentionally unclear and/or in conflict with each others just like the already mentioned claims are, no problem). Many voters may have interest but not sufficient knowledge and time/ interest to draw rational conclusions. Politicians may well drive only the short term interests of their own party and themselves (instead of the society as a whole) (big parties usually have even rational (selfish) reasons). Media may also be mostly interested in short term juicy stories. And experts too may have mixed interests. I however note that there is always some tendency to find solutions that are good in theory and in practice (and tendency to avoid solutions that have clearly been proven wrong). Decision making will go slightly in that (rational, sensible) direction if all the facts are made known and especially if clear descriptions and clear justification of them are available. That means that despite of the demagogic nature of the discussion also rational argumentation does have a place in the process. Better to throw the argumentation in although the discussion and its outcome may not fully follow the intended logic.

The complaint from those circulating the IRV repeal petition is that there shouldn't be any ranked ballots, and that the plurality winner with 33% of the vote in the first round (and the essential Condorcet-loser) should have been declared elected. There is no momentum toward a Condorcet approach currently. I haven't heard more than a couple of people in Burlington suggest that the actual Condorcet winner should have won, because he was a weak Condorcet compromise in third place in the initial tally. I suspect that if Burlington had used Condorcet rules and the candidate in third place in the initial tally had been declared elected, there would be even more vociferous calls for repeal in favor of plurality or runoffs.

In Burlington at least the arguments for Condorcet should be straight forward. People are already ok with ranked ballot based voting. Many of them may feel that in the last election the Condorcet winner should have won. From this point of view Condorcet is just a small modification that fixes this problem. Many voters may support going back to the old system since that would (at least seem to) fix the problem of failing to elect the (beats all) Condorcet winner. It would make sense to make them aware that there are also other ways to solve the problem (= just fix the tabulation method).

That's stupid enough to get me a bit angry. They see a problem with IRV results. Going back to pick-one voting is sticking their heads in the sand and denying to see the problem. Because we have the full data dump from the rankings ballots we can do analysis and figure out what happened and how IRV was wrong (and how pick-one would have been wrong), but if they take that away then we just won't know again. Problem hidden! I really hope the forces of stupid don't win. Good luck up there guys. If there was going to be a big public meeting, I might even be tempted to drive up from Boston.

I'm afraid the method is not monotone: If a member of S moves up on the ordinal ballots, it is true this move will increase her chances of winning if L(S) is chosen over A, but it might make it so that L(S) is not chosen over A.

Juho wrote: They also said: Condorcet-Schultze med 30% kvotering = Condorcet-Schultze with 30% quotas I just wonder if that adds something to the basic Schulze method. That means that 30% of the people on the list has to have some property. I'm not sure what that property is, but I guess it refers to matters of gender - at least 30% of each. I don't see any mention of how they're going to achieve this. If I were to make something like that, I would probably divide the result into ordered lists, based on the property (e.g. gender), then go straightforward down along the social ordering until either group decreases below the quota. At that point, pick the highest ranked from the list of the minority in question until that group is no longer below the quota. One could probably devise even more complex solutions involving global optimization, particularly for methods that return a cardinal social ordering (a ratings ballot as output). For such an ordering, one could simply phrase it as an integer programming problem: maximize the total rating, subject to that one may not pick more than the number of seats and that no group may have less than 30% of the seats. I would be surprised if that's how they do it, though, in particular since the Schulze method doesn't return a cardinal social ordering.

[EM] Utah Republican Party Scraps IRV Voting Method
Nice to know someone has some common sense to scrap IRV voting. I found out that NYC tried IRV in the 1930s and scrapped it too. Also Burlington VT and Aspen CO have ongoing efforts to scrap it and several other locations recently made the wise decision to scrap possibly the only alternative voting method that has more flaws and fails more of Arrow's fairness criteria than plurality voting. http://utahpolicy.com/featured_article/utah-republican-convention-change-could-change-strategy-candidates Some people are waking up to the fact that IRV/STV is a threat to the fairness and integrity of elections.

Abd ul has convinced me that regular top-two runoffs are good too. Top two runoff, of course, shares the center-squeeze problem that IRV suffers from, but, interestingly enough, that problem may not be as serious if write-in votes are allowed in the runoff, as they are by default in California and perhaps some other jurisdictions. Not widely known is the fact that the spoiler effect is connected with partisan elections. IRV in nonpartisan elections seems to reproduce Plurality closely. With top-two runoff in nonpartisan elections, the runner up in the primary wins roughly one-third of the time, per a study by FairVote. However, with IRV, these comeback elections hardly ever occur. IRV does fix what I call the first-order spoiler effect, where a minor party candidate draws away votes from a major party candidate, causing the less popular of the major party candidates to win. However, as a recent Burlington election shows, IRV can award victory to a candidate who would, by the votes expressed on the ballots, lose in a direct contest to an eliminated candidate, because of the peculiar significance that IRV gives to the first choice. It is entirely possible that without the promise of IRV as a fair system, the same configuration of candidates would not exist, and the more popular candidate would have won. There is another system that uses the same ranked choice ballot as IRV, but that is probably much better at handling the center squeeze situation, and that was at one time widely used in the U.S. (Far more widely than the recent IRV fad.) That's Bucklin voting. It could be called Instant Runoff Approval. It's much easier to canvass than IRV, the totals for each rank are simply collected from each precinct, and the handling, if there is no majority in first preference, is simple addition; the difference from Approval is that the approvals are ranked, so additional approvals are only considered if nobody gets a majority in first preferences. Why was Bucklin rejected? Partly, it may have been for similar reasons to the prior and present rejections of IRV. IRV has been sold on a false promise: to find majorities without runoff elections. Bucklin was sold in the same way, and it fails to find majorities reliably for the same reason as IRV fails: people don't rank enough candidates. This has been a known problem with STV for more than a century, and whenever a candidate doesn't get a majority in first preferences, it is *normal* for IRV to never find a majority even after vote transfers, the IRV majority is a faux majority, a new invention, a last round majority, based on an entirely new concept of a majority that isn't the traditional one: a majority of ballots case. Bucklin is based on majority of ballots cast, as are standard repeated ballot systems. All ballots are considered. Bucklin, because of the lack of candidate eliminations, which really means ballot eliminations in actual practice, is more efficient at finding majorities, however, because it will find votes concealed under votes for a leading candidate. We tend to think of partisan elections, for some reason, where a voter for one of the top two candidates would one rarely also approve one of the other top two. But in nonpartisan elections, which are the vast majority of recent IRV applications, a supporter of one of the leading candidates might well express support for another leading candidate. Not highly partisan supporters, but general voters. IRV conceals these votes, Bucklin finds and counts them. The error with prior implementations was in the false promise: when it was realized that Bucklin wasn't actually finding majorities in some of the places where it was used, because of enough voters doing the traditional vote-for-one thing, Bucklin was dumped entirely. It, as also happened with IRV in some prior situations, it was replaced with top-two runoff, which usually finds a majority. Instead, Bucklin should have been used as a method of avoiding unnecessary runoffs. I like to think of this as the voter's strategy. With Bucklin, I will unconditionally vote in first preference for my favorite. There is never a reason not to. (With IRV, there can be circumstances where voting for your favorite will turn out to be foolish, it can cause a much worse outcome, it can even cause your favorite to lose. That's what non-monotonicity means.) Then, as to adding other, lower-ranked approvals, the

(Single Transferable Vote is considerably better when used for multiwinner elections, though there are better methods still, for sure. True multiwinner STV has been rejected after use in the U.S., but not for good reasons. It was rejected because it resulted in fair representation for minority groups. Most people who oppose IRV/STV today support proportional reprentation, but IRV has not achieved that in most places it has been tried and there are other methods, such as the party list system, cumulative voting, etc. that achieve it without being nonmonotonic and without the spoiler effect and without the complex transparency-eviscerating central counting that IRV/STV produce. IRV/STV do not count all voters' 2nd choices, even when voters' first choice candidate loses, and so is a fundamentally unfair method that tends to elect extreme right or left candidates and eliminate the centrist majority-favorite candidates, just like it did in Burlington, VT mayoral contest. I urge election activists opposed to IRV not to jump for the temptation of praising those rejections as wise. They weren't. They were racist and prejudiced in other ways against the fair choices of the voters. In Ann Arbor, MI, IRV was rejected on arguments similar, apparently, to some of those being advanced in Burlington now: it deprived the Republican of his rightful victory over the Democrat, which had been previously happening because of vote splitting in a college town between the Democratic candidates and the Human Rights Party candidates. Correction - In Burlington the Democrat was the centrist majority-favorite (Condorcet) candidate and the Republican acted as a spoiler, causing the Leftist candidate to win. Republicans have not won any mayoral election in Burlington for over a decade and was the spoiler. Almost all the folks who voted their true preference for the Republican, caused their last choice (the most liberal candidate) to win. For a simple short understandable film explaining the vote counts in Burlington that was just finished today, see this: http://www.youtube.com/watch?v=bPCS-zWuel8 However, the situation in Burlington is pretty different: the problem there is that there are three major parties there, and IRV does very poorly in that context. It worked in Ann Arbor, and, for that reason, a referendum on it was scheduled for when the students were on break, mostly out of town!) IRV does poorly wherever there are three strong candidates and the spoiler problem pops up.
