[EM] Condorcet meeting

[Colin Champion]

I’m not persuaded of approval voting. My guess is that voters will 
bullet-vote for the candidate they like best among those they know 
about; candidates will encourage bullet voting on their own behalf; 
pundits will have nothing better to say, and voters will have no motive 
to award more than the minimum number of approvals.
    A danger of quadratic and entropic measures is that they don't 
impose the constraint that the number of survivors has to be small 
enough to make ranked voting effective on the second round.
