On second thought, the proof of the pudding is in the eating. Since he was, by his own admission, a constitutional history Professor, where is his research? What issues did he study in depth in his research areas? How well did he demonstrate his knowledge and creativity in those areas? What new perspectives did he develop that increased our understanding of the Constitution?
If he made all A's in school but can't create new knowledge as a Professor, it is a little disconcerting. If he made a spectrum of grades but was able to create and publish high level scholarship, he could be called a late-bloomer.
So far, there is no evidence of any scholarly publications at all.
