Don't be surprised if he is running for President in the GOP primaries in 2012.
He is still far, far behind Sarah Palin, Mitt Romney, Mike Huckabee and others - but - there is rapidly building a buzz around him. He's a darkhorse right now, but watch for him in the future.
I think he just became one of the TV networks "go-to guy" for logical, rational, and impressive criticism of this Administration.
