Prediction: McCain will dump Palin
I'm not sure how this would work, though: now that the conventions are over, what's the mechanism for replacing a VP nominee? And I bet many ballots have already been printed. But the fact that it'll cause confusion and difficulty will only make it a more attractive option
I'm enamored enough of my theory that I'm going to place a bet on intrade. But it's a bit tricky funding an account, so I haven't done it yet. It's a longshot, but it will be a small bet and if I'm right I'll have some great bragging rights. And if I'm wrong, Palin's presence will probably drag McCain down, which will more than compensate.
