Anybody can make a prediction and we've all seen how wrong polls can be. You can guess all you want.
The truth is, we won't know until the election. Whatever the outcome, it's a cinch the losing side is going to cry foul. Just look at how the Repubs were complaining about a rigged vote in Wisconsin, before they found out they won. Then, all of a sudden, the election wasn't rigged and the results were accepted.
