Not supposedly, he did. There isn't much available with respect to his competence, however, there was a link to tests he purportedly gave to his classes going around the web a couple of years ago. I apologize for not having a link to them, but I remember them as being trite, trivial, lazily written, and obsessing on racial issues.
In other words, he was like certain other useless liberal college professors who were just killing time between political jobs, or waiting to get into one..
Thanks for the information; it (BO) sounds so shady...
