Two additional points. First, Coburn is an exceptionally forceful social conservative. To the extent McCain needs to keep some of those voters out of Huckabee’s camp this will help. Second, getting the endorsement tells me the McCain camp has woken up. I sensed that they had not much of a game plan in Michigan other than “we won NH!” and this may be an indication they see the need for a forceful, message intensified few days to hold down SC. He’s ahead in recent polls ( the polls generally got Michigan right by the way) but three days is now evidentally a lifetime in politics so we’ll have to see if his advantage holds up.
