We should know the results fairly early. Florida, Ohio, North Carolina, and Virginia polls all close at 4 PM PST.
The media are pretending that Pennsylvania is in play, I think this is just to keep us in front of our TVs. There are 9 states in play: Colorado, Florida, Iowa, New Hampshire, Nevada, North Carolina, Ohio, Virginia, and Wisconsin.
Of these nine, I think three will go to Obama quickly: Ohio, Nevada, and New Hampshire. That leaves him just 6 electoral votes short of victory.
If Romney does not sweep Virginia, North Carolina, and Florida (all close at 4 PST) then it is over. Florida appears to be close, Virginia leans Obama, and North Carolina leans Romney.
Predictions: Odds are at least 50 to 1 for an Obama victory. And we will probably know the definitive answer by 8PM PST.
None of this is meant to imply that it makes one whit of difference who wins. While the media hypes this election as one of the most vitriolic in history, I think we have never had an election where the candidates agreed on so much. And maybe that is why they resort to name calling, there are no differences in their political leanings to debate.
