Here's what I meant to say:
Preference Majority Criterion (PMC):
A method fails PMC if it's possible to contrive a configuration of candidates, voters, and voter-preferences such that a set of voters consisting of more than half of the voters prefer X to each of the other candidates, and it isn't possible to contrive a votes-configuration such that everyone votes sincerely and X wins.
[end of special-purpose ad-hoc Preference Majority definition]
So you (James) have wriitten one, and so have I.
