Hi, Summary of my point:
This election has demonstrated quite nicely that those Debian developers who voted prefer Martin to any other single candidate. In other words, if you held a vote which would ask whether to annul the vote and replace Martin with Brandon, the majority would be against that proposal. I do not understand how you can, given that fact, declare that Condorcet voting is fundamentally flawed. For the sake of argument, I am going to disregard the fact that changing the rules retroactively when the result doesn't suit somebody just isn't done in ANY democracy which deserves that title.

I do not share your opinion that replacing IRV with its multiple-vote equivalent would be an improvement in any way. On the contrary, you state yourself that "Item [4] allows voters to mislead other voters." That is one of the problems Condorcet is designed to avoid, because under Condorcet, "strategic", i.e. insincere, voting just doesn't work. > Anyway, I'd have plain Condorcet would fail the monotonicity > check. I don't understand that sentence. Please demonstrate how Condorcet would fail the monotonicity criterion instead of just asserting it does, esp. when electionmethods.org says it does not (and indeed any simple analysis of Condorcet says the same). On the other hand, we have real-world data which show how IRV does fail monotonicity, and frankly I don't see how replacing a one-off IRV ballot with your iterated version would change anything except incite even more people to vote insincerely. Yor analysis completely disregards the fact that there CANNOT BE A 100% FAIR ELECTION because the voters' opinion can be ambiguous. That has been mathematically proven 200 years ago. All anybody can do is to invent a few desireable properties and a few voting methods, decide which properties are more important, and decide which voting method best fits that list. Your analysis goes off on a tangent WRT "electing zero winners" and one- or two-candidate elections. Neither is on-topic here. The discussion about this already happened, a few months ago, and it doesn't make much sense to repeat it. -- Matthias Urlichs | noris network AG | http://smurf.noris.de/ -- If you want your program to be readable, consider supplying the argument. -- Larry Wall in the perl man page
