Obama was never a professor; he was a lecturer.  He did not have the qualifications to be a professor.  Obama never published a single law paper.  He was hired by the University of Chicago when they learned he had been given a book contract on race and law directly after graduating from Harvard.  There was no book – just the contract, which he later reneged on.  This is not the normal level of accomplishment for a University of Chicago professor or even lecturer.

So what did he teach at UChicago?  Obama did not specialize in the Constitution.  Obama cared about and taught only one subject: race.  One course was about race in the Constitution.  It is on this flimsy basis that he attempts to pawn himself off as a constitutional scholar.  Obama is a narcissistic liar extraordinaire.
