I don't mean to discuss methods with a strong random component. While it is true that no majoritarian method will elect the compromise when there is a majority favorite, I think it is reasonable to claim that (all things being equal, if that is possible) the majoritarian method will elect a compromise more often in the absence of a majority solidly committed to a single candidate, than the method which is not majoritarian. I am assuming voters are strategic. Kevin Venzke ---- Election-Methods mailing list - see http://electorama.com/em for list info
