Every person in the GOP that wants to have a political future is going to run away from VP slot on his ticket. You'd spend 3/4 of your time trying to explain away his latest ridiculous statement, and the other 1/4 trying to repair relationships with everyone he offended, yesterday.
Think about it: At the convention, no Romney, McCain, GHW Bush, GW Bush, no Jeb, most of the other candidates this year staying away. He's a trainwreck waiting to happen, and they know it, and they don't want to be tied to the aftermath.
