Good point.
Thus far, I think he has proved to be everything Republican voters feared. How can they stand behind a man who says whatever his audience wants to hear? Is he a conservative? - Yes on Monday when he wants "to energise the base". - No on Tuesday when he wants to capture undecided voters.
I'd be sorely troubled if I was inclined to vote for a Republican ticket. What would a president Romney do? Whatever seemed expedient on that day, of course.
