Basically, by what you describe....an “empty suit”?
The fact that he wasn’t going to get tenure as a professor while he did that gig there in Chicago....says something. I would suspect at best...he was a grad student pretending to be a professor, and he’s repeating the whole episode again...a grad student pretending to be president.
He’s admitted he’s lazy and blamed that on Hawaii. Perhaps he has attention deficit disorder or some other new age brain problem.
