Heck - with voter apathy the way it is, every active voter's opinion is already worth far more than 'Joe six-pack's'.
After Florida and the last election, we'll prolly see fewer voters. A number of my friends just shrugged and said 'see? Our votes don't matter' or the equivalent (the fact that they said crap like this KNOWING they'd get an earful from me shows the depth of this belief).
Who knows - if we don't get a 'fixed' election, the weight of your vote may be higer than you imagine...
