The answer, of course, is yes!
Mike Huckabee's charisma and amazing communication skills allow him to essentially live off the land. While he would benefit greatly from a win -- and the money it would inject into his campaign -- his communications skills mean he can survive without a win.
Nobody expected Huckabee to be where he is tonight, so he has everything to gain -- and nothing to lose. A second-place finish tonight certainly wouldn't be embarrassing for him.
While both candidates are, no doubt, desperate for a win tonight, John McCain needs this victory more than Huckabee does.
