I doubt it. I still think his running mate will be a classical RINO. The establishment will NOT allow someone like Palin, Cain, Ryan, or Rubio, or any other candidate perceived to be part of the “tea party” on to the ticket. (They are still mad that McCain picked Palin, they wanted Jeb Bush).
Liberman and Jeb Bush have also been batted around as a Romney VP possibility.
I actually agree with Psalm here. Mitt is friends with Jim DeMint, and there has been a longstanding whispering campaign that Rove believes DeMint can be Romney’s Palin.
I expect Romney would pick someone VERY Conservative so that he can go off the left end of the earth if he needs to in order to win the General.
