Here's a quick look at what will happen when tomorrow and what will tell you how the election is going early on.
7PM ET: Polls close in Virginia, Georgia, Indiana, Kentucky, South Carolina, and Vermont. Five of those states aren't in play and should be called instantly. The big one here is Virginia. Expect the networks to label it as "too close to call." It will give us our first glimpse of what kind of electorate is turning out to vote. The exit polling data for Virginia will be very telling. If the electorate matches what polls have been predicting, it points to polling not being off, meaning Obama is likely going to win (not necessarily win Virginia, but the election at large). If the electorate doesn't match up, and is more favorable to Romney, we're in for a wild night of surprises.
