A great site that explains how the Electoral College works and presents a nice map of likely votes this fall, based on state polls instead of national polls, which seems to be a much more relevant way to do things.
As someone pointed out somewhere but I forget where, we don't have one election for president, we have 51 (including D.C.), with some being much more important than others.
Current tally:
Kerry - 302
Bush - 232
Needed to win: 270
If you live in a "weak" or "barely" state, you're on the front lines.
Oh, and for any of our friends overseas who may be reading this, please Tell An American To Vote! (Unless they're a Republican, in which case you needn't go out of your way.)
