Condorcet is bad for the candidates who would have won under plurality
runoffs or IRV but lose under Condorcet!

I've also met a number of people, who when I talked about IRV, they were
deathly afraid it would have allowed Nader to win the presidency. IRV never
helps a weak middle win, but Condorcet will. It actually took me a while to
convince my cousin that he actually preferred Bush to Nader second. He
assumed he would somehow be forced to vote Nader second.

Well, this shows that in a Condorcet election voters must take lower
preferences more seriously than in IRV.

I'm still counting in the month election - 28 ballots so far. I'm hoping for
50 - everyone keep sending them!!!

I'm not very interest in technical subject polls since I'm asking everyone I
can get to participate.

I'm afraid I haven't paid enough attention to understand Voter's Choice.

I'm basically content now to work with simple Approval and actual runoff
elections.

If we're going to do systematic test elections, I won't participate to
include Approval unless single-vote Plurality is also included since they
are the ones I'm interested in comparing now.
