That's his secret weapon. Outside of the Northeast, nobody knows squat about the guy. He might even be associated with 9/11 in some people's minds.
If he stuffs a billion dollars into this, he'll be able to define himself as anything he wants to. It will take a massive effort on the part of the Republican nominee to make sure that real Republicans know that he's an idiot.
I just hope somebody's got some great dirt on him for October, 2008. Maybe it'll even be Hillary who takes him down.
