That scant material that has been seen purporting to be the work of Obama in college would not have made it in my high school. It was crap then and would be crap now. That's why it's not around for you to see and possibly evaluate. His "college work" consisted of a few (mighty few) round-table seminars at Columbia, and more of the same at Occidental for which Columbia gave him credit.
This is a lazy, possibly quite dumb low SAT guy with a gift of slick liberal-pleasing gab ... and no "black" overtones.
Apropos of nothing in this post: why does no one ever ask why he is not still a member of the Illinois Bar?
I read something supposedly written by him...who knows if he wrote it or not? What I read was not illiterate.
