Obama went to the liberal arts part of Columbia... Columbia COllege. I dont think it has more than a few thousand students.
I find it inconceivable that no one would remember him. Something is definitely fishy.
I went to college years before he did and any number of my professors are still alive.
"One person who did remember Mr. Obama was Michael L. Baron, who taught a senior seminar on international politics and American policy. Mr. Baron, now president of an electronics company in Florida, said he was Mr. Obamas adviser on the senior thesis for that course. Mr. Baron, who later wrote Mr. Obama a recommendation for Harvard Law School, gave him an A in the course. . . . Michael J. Wolf, who took the seminar with him and went on to become president of MTV Networks, said: He was very smart. He had a broad sense of international politics and international relations. It was a class with a lot of debate. He was a very, very active participant. I think he was truly distinctive from the other people in that class. He stood out.
