Not if McCain throws her under the bus and endorses Romney, a very real possibility.
Remember, loyalty is not exactly one of McCain's strongest suits, and that's being overly kind to him.
That’s one of the few things you and I agree on: I don’t trust McCain as far as I could kick him. No doubt in my mind he’d endorse Romney over Sarah. And I don’t trust him to not run as an Independent when he loses to JD. Of course, thank goodness certain laws in AZ prevent him from doing that, according to some freepers.
