Hetty...notice how the University uses a little p with professor (in other words, a college teacher), and a big L with Lecturer. Obama no longer uses the professor title, but it took Hillary Clinton questioning his credentials for that to change.
Chicago's own Sun Times reporter, Lynn Sweet, confirmed that Obama was no Professor, and felt the University statement "did Obama no favor by saying he was a law professor when he wasn’t".
I feel vindicated too!
