Barbour is definitely a loser after the uproar over his pardons just before he left office.
I wonder if Romney will feel pressure someone from a mainstream Protestant background--if he chooses a Catholic it would be the first ticket without a Protestant on it. Maybe that doesn't matter--we have the first Supreme Court which has no Protestants on it and few people even notice.
I don’t think he needs a protestant, but he needs a Christian for sure. If not Huntsman, it will be either a Catholic or mainline protestant.
