If McCain has a choice, then yes. But if it goes to brokered, which it might, Romney'll have the balance of power and could decide electable McCain works better than dead loss Huckabee.

Romney isn't stupid, he knows Huckabee can't really win, he probably knows he can't really win, although I'm not sure his conscious was thinkng that way when he was running.

We'll see. Interesting times...
