As you acknowledge, IRV does not satisfy monotonicity when there are three (or more) candidates. Top-two runoff is equivalent to IRV when there are three candidates. So if you're going to claim IRV is unconstitutional due to non-monotonicity, you would, at least logically, have to deem top-two runoff unconstitutional as well. The affidavit from David Austen-Smith that you are hosting on your site shows you a simple example of this: http://electionmathematics.org/em-IRV/DefendantsDocs/11AffidavitofDavidAusten-Smith.pdf >> Note also that other arguments by the "MN Voter's Alliance" would, if >> successful, would render *any* voting method that involves putting >> marks next to multiple candidates -- IRV, Bucklin, Approval, >> Condorcet, Range -- by its nature unconstitutional. > > Really?!* What arguments are those? I missed that. That would be their response to argument #1 on their webpage against IRV: http://www.mnvoters.org/IRV.htm They claim that the act of marking multiple choices on the ballot is effectively allowing the voter to cast "multiple votes," and therefore, unconstitutional. If that argument is successful, it would jeopardize any alternative to plurality in Minnesota. >> They are also arguing that, because IRV satisfies Condorcet Loser and >> therefore requires the winner to show *some* majority over another >> candidate, that it could therefore lead to "tyranny" of the majority. > > Who is "they"? And where did "they" argue what you claim in your above > sentence? This is argument #2 on their page. Here's the link again: http://www.mnvoters.org/IRV.htm Here's is the relevant snippet: "2. IRV advocates say the current primary system is flawed because: "it undermines the 50% +1 majority-winner requirement." Our response - The objection to a plurality system is misguided. The Founding Founders gave us a Constitutional Republic, not a majority-rule Democracy, because they knew pure majority rule often leads to tyranny." They then proceed to contradict themselves and claim that, actually, IRV doesn't require a majority. So are they for some kind of majority threshold or not? I don't think they know what they believe. They're just throwing everything at the wall to see what sticks. >> These people are throwing everything at the wall to see what sticks. >> The fact that you've made allies with them is telling. > > Oh, OK.

Hmm, "emotionally attached and impervious to facts.". I detect some psychological projection here. ---- Election-Methods mailing list - see http://electorama.com/em for list info
