I find it amazing how many people seem unwilling to get their heads round the actual voting system you have, in which the popular vote as such just doesn't make any difference.

As I understand it, most of the country is sewn up, in the sense that either Bush or Kerry will be well ahead in the vote that determines electoral college votes. Wherever this is the case, it won't make any difference at all if a fair number of people switch their vote to Nader or the American version of the Monster Raving Loony Party (though I suppose it'd have to be called something different, to avoid getting confused with the people in power).

It's only in the relatively small number of "swing states" that that kind of thing could make any difference to the outcome. Or in States where the electoral vote is divided up to reflect the popular vote, rather than being allocated on a winner takes all basis - I think there are some like that.
