Yes, he should have. But Cruz won anyway. I won't hold this lapse against Perry, and despite the reservations of some on this board, Perry is my kind of 10th Amendment conservative.
Perry will my vote any time he asks for it.
Perhaps Perry supported Dewhurst because he wanted to get him out of State government. He would be less of a pain to Perry if he were in Washington and certainly couldn’t have been a worse Republican Senator than Kay Bailey.
