Trying to sort this out as to Condorcet and LNH:

Seems that cycles are involved before, after, or both. And the voters change their votes, getting more affect on result than they might expect. So what, assuming the counters properly read the vote?

I agree with those who expect cycles to be rare. Still, it is the more important races that are more likely to result in cycles.

What I see as important is that, assuming analysis of the election is done both officially and by others, it should be practical to decide whether the official result was correct, considering the N*N vote count. In other words, the official analysis should not be complex - especially not to gain trivial improvement in quality of official result.

kabuki dance of transferred votes.  and there is an *arbitrary*
evaluation in the elimination of candidates in the IRV rounds: 2nd-
choice votes don't count for shit in deciding who to eliminate (who
decided that?  2nd-choice votes are as good as last-choice?  under
what meaningful and consistent philosophy was that decided?), then
when your candidate is eliminated your 2nd-choice vote counts as much
as your 1st-choice."

Regarding IRV's "philosophy": each voter has single vote that is transferable according to a rule that meets Later-no-Harm, Later-no-Help and Majority
for Solid Coalitions.

I rate IRV (Alternative Vote with unlimited strict ranking from the top) as the
best of the single-winner methods that meet Later-no-Harm.

Are there any other voting methods besides IRV, meeting the

my understanding is that the later-no-harm result happens only if the case of a Condorcet cycle (the prevalence of which i am dubious about). where there is a Condorcet winner and that person is elected, is there still possible later harm?

i hadn't thought of it before but i s'pose that since Condorcet *does* give preference to centrist candidates over solid coalition candidates (in comparison to IRV rules). i knew before that Condorcet sorta favors centrist candidates because voters in either the left or right fringes (that do not pick the centrist candidate as their 1st-choice) likely pick the centrist as their 2nd-choice. that's nice for political interests of centrist voters, but that is no reason to pick an election method. the reason that IRV or *any* non-Condorcet method is problematic for the interest of democracy is that any candidate elected that is not the Condorcet winner is elected despite the fact that the majority of voters expressed that they wanted someone else *specifically* on their ballots.

when IRV or Borda or whatever happens to elect the Condorcet winner, they seem to do pretty well. when they fail to do that, voters have reason to wonder: "didn't more of us prefer that other guy? how'd this guy get elected?" isn't that what democracy is about?: if more of us prefer Candidate A to Candidate B, then it isn't Candidate B who gets elected.

other than the possible cycle, in which some kinda pathologies can happen, i still don't see a pimple on it.
