What you have to remember about Obama is that when he went to college racial quotas were still legal. He got into college because he was black. He got into law school because he was black. He got onto the law review, because he was black. But remember to liberals just letting them in is not enough... they have to graduate too! So regardless of how poorly they do... they are passed through.
I would be surprised if Obama has much more than a high school education. Remember, that Obama himself admitted he was high on cocaine through most of college.
The kicker is that he is way more white and arab than black. (quadroon, octaroon?)
