This is why I was careful to distinguish between a voting method and an election method (or system). I would never use Borda to elect a government, BUT... when there was no clear majority and my purpose is to quantify a "concensus", a Borda count is a quick and efficient way to do that. For example, if I ask 65 sportswriters to rank 117 sports teams in a league, I might use some form of Borda as an alternative to just averaging the ordinal rankings they provide (which has worse problems, especially since most won't bother to do it right after the 25 teams they know something about). It is useful in cases like this because the objective is not just to pick which team is number 1, where just 33 of 65 "votes" would suffice, the objective is to order all 117 teams. (Personally, I woudn't use pure Borda for that, either, but what I would use is probably so similar to it you couldn't tell the difference). ---- Election-methods mailing list - see http://electorama.com/em for list info
