Consider the following example: 51 ABC 25 BCA 24 CBA
Voter Space Borda gives A voters a score of 51*49-49*51=0, while B voters get a score of 25*75+(24-51)*(51-24) = 1199 which is greater than zero. If the A voters had truncated or voted CB as often as BC this wouldn't have happened. This can be viewed as a clone problem, too, so apparently VSB doesn't completely neutralize clone sensitivity. However, it is true that Voter Space Above Median Approval (VSAMA) does satisfy the Majority Criterion, and also strongly (if not completely) discourages betrayal of favorite. If I had to have a pure ranked ballot method named after me, I would probably choose VSAMA. But, fortunately my name is not VSAMA :-) Forest ---- Election-methods mailing list - see http://electorama.com/em for list info
