I suspect he was in the bag for Romney all along. The both put on their magic underwear one leg at a time.
He just didn't want you to think he was supporting Romney ONLY because they share the same religion. So, he decided to pretend to support another candidate but to assure his real candidate would win in the end he knew he'd have to choose the one least able to win in the primary.
I think the first one he supported was Michelle Bachmann (I could be mistaken about this one) but after she dropped out he decided to fake support for Rick Santorum.
Well the three people in politics I like are Sarah, Paul and Newt. Beck turned on all three, screw Glenn Beck.
