Anti-Climacus

LINK: Crooked Timber has an interesting post on the consequences of Condorcet- or IRV-style voting systems. I always took it to be a sufficiently good argument against them that they presume, to be effective, that everyone has more than one possibility that they like. Should someone only have, say, a #1 option, while everyone else has three options they like enough to rank, you've just deprived the first person of an equal vote to all the others. This doesn't, of course, happen under plurality-rule voting.
