Everyone seems to have missed understanding my point which is that IRV is nonmonotonic, plurality is not. In any one election, the voter in plurality retains the right to know which candidate his vote helps. In IRV it's anyone's guess whether a vote will help or hurt a favorite candidate's chances of winning. For instance in Aspen CO's most recent IRV election, if 75 *fewer* voters had voted for one candidate that candidate would have won. That probably happens a lot in IRV but IRV is so darn complex to count and analyze after elections that no one has time or data to analyze all IRV/STV election vagaries. >>>>> 2. allows all voters the right to participate in the final counting >>>>> round in the case of top two runoff or primary/general elections >>>> >>>> but IRV does that in an instantaneous way UNLESS some voter changes FALSE statement by ?? IRV always removes voters involuntarily from the final counting round, unlike plurality voting where all registered voters are allowed to participate. Voters are involuntarily excluded whenever: 1. they fail to fully rank all candidates and their choices don't make it to the final round, or 2. they rank all candidates possible to rank on the ballot, say 3, but there are more than 4 candidates in the contest with supporters. The only way IRV voters get to participate in the final counting round is if they vote for one of the candidates that happens to survive to the final round and since sometimes IRV eliminates the most popular candidate like it did in Burlington, that can be difficult to determine. >>>>> 3. preserves voters' right to understandably verify the election >>>>> outcomes because the counting is simple enough for them to do, >>>>> precinct summable >>>> >>>> so does Condorcet. Yes. Of course. IRV/STV really are the only voting methods that are worse than plurality voting, that I have heard anyone promoting. Reminds me of the "big improvement" of DRE paperless e-ballot voting which was pushed for by some of the same players who are now pushing for IRV, including Common Cause, LWV groups, Fairytale Vote, etc. >>> >>> And Condorcet gives a more accurate view since the ballots more >>> completely state voters desires and all that they say gets counted.

Yes. I agree. Imagine counting all ballots in DC and carting all ballots to Washington DC to check the accuracy of the tallies to elect the President using IRV!

I don't know about that and am doubtful about the veracity of what you say as it does not seem logical or expected. We can agree to disagree for now as I admittedly don't have time to investigate fully. >>> >>> Topic seems to be that a second look at a ballot is required in IRV after >>> it is determined that the top rank lost. In Condorcet all the looking is >>> done in one pass. Yes. I totally agree that Condorcet is far superior to IRV/STV and would solve the spoiler problem, unlike IRV/STV. IRV/STV is fundamentally unfair because a large group of persons whose first choice loses, never has their 2nd choice counted, unlike some other voters. It's a highly inequitable method. -- Kathy Dopp Town of Colonie, NY 12304 phone 518-952-4030 cell 518-505-0220 http://utahcountvotes.org http://electionmathematics.org http://kathydopp.com/serendipity/ Realities Mar Instant Runoff Voting http://electionmathematics.org/ucvAnalysis/US/RCV-IRV/InstantRunoffVotingFlaws.pdf Voters Have Reason to Worry http://utahcountvotes.org/UT/UtahCountVotes-ThadHall-Response.pdf Checking election outcome accuracy --- Post-election audit sampling http://electionmathematics.org/em-audits/US/PEAuditSamplingMethods.pdf ---- Election-Methods mailing list - see http://electorama.com/em for list info
