If Perry were to drop out and endorse Gingrich, it would be in large measure to get back at the Bush’s. Bush 41 is the classic establishment republican who endorsed Romney, verbally downplayed Perry, and did not hide his dislike for Newt. W and his administration were not always kind to Perry, either. It would be a good smackdown from Rick back to the Bush’s and could put him into consideration for the VP slot as the anti-establishment, anti-Bush VP with extensive executive experience.
Excellent point. Let's get Perry on board asap. His fans are full of a lot of energy, too.
