It's less than an hour to election day here on the East coast... so here goes:
Obama - 338
McCain - 200
Bonus prediction: At least one major network will declare Obama the winner BEFORE polls close on the West coast, maybe as early as 9:30 PM. I just don't see how this is going to be all that close, with key wins for Obama coming in Virginia, Florida, and Ohio.
Update 8:32 AM 11/4 - Forgot to throw this in, but hey! it's not too late: Also predicting the Democrats will control 57 Senate seats at the end of the day.
