...but it's pretty much a given.
Andrew Gelman of Columbia University has taken a recent set of our simulations to look at what may happen conditional on the outcomes of the first states to close their polls at 6 and 7 PM. The bottom line? If those states go roughly as expected (meaning, say, an Obama win in Virginia and a close race in Indiana), we can conclude with almost literal 100 percent certainty that Obama will win the election.
Gotta love them 'puters.
