Wasn't Obama a lecturer in Constitutional Law?
Yes.
Sen. Obama, who has taught courses in constitutional law at the University of Chicago, has regularly referred to himself as "a constitutional law professor," most famously at a March 30, 2007, fundraiser when he said, "I was a constitutional law professor, which means unlike the current president I actually respect the Constitution."
