Or, better yet: he should publicly decline the invitation (on camera) while scratching his nose with his middle finger. In short, he should pull an Obama.
Obama has no class and from what I have heard about this guy, he's a good guy. No one’s perfect and I know the MSM will dig something up on him soon. May be he picks is nose or may be he drinks Old English 800 while eating tacos or something. Whatever it is this dude will be toast if he pushes Obama. The MSM will see to that.Just ask Joe the Plumber and Sarah Palin.
The Professor is just like all other liberal academic types, he's too smart, and good to play by the same rules you and I do. Add to this his dislike for white folks, you get a mess.
