All of my favorites aquitted themselves well, although Cain clearly fumbled the 'who's your favorite fed chairman' question. Paul got that one right.
Not that it'll matter in the end though. This race isn't going to be determined by any more debates - any damage that will be done has been done.
How can you "fumble" a question by giving a direct honest answer. Cains answer was based on his experience actually working with Greenspan. Now you might disagree with Cain's answer, but he certainly didn't "fumble" the question.
