Of course I don't know Obama personally so I really can't tell if he's a racist. In fact, I really think that word has lost all it's "punch" thanks to non-stop usage by NAACP and LaRaza types.
However, if George Bush sat in a white church like Wright's for 20 years he would have never even been nominated much less elected President.
Yes, BO is a racist. He chose to attend that church.
