I wouldn't be dumbfounded at a Romney nomination, but I would be surprised. The guy looks like a cartoon president. And he waffles more than BDW. Who would elect this man?
George Bush looked like a buffoon who couldn't string two sentences together to me in 2000. But, he had the republican establishment behind him. And people voted for him.
I can see Romeny being nominated. As the lesser of all evils; he's a flawed candidate to be sure.
