Must be because he is really doing a fine job and "the man" AKA whitey, is just holding him down.
I am pretty sure more whites voted for Obama than blacks. Not really mathematicly sound if people think that just the "black vote" was enough.
Maybe it's just that those white people that voted for him actually followed up on where their vote went and are now pretty pissed about it. I am pretty sure the majority of white people who voted for Obama didn't vote to further the cause of black people or minorities as a whole. Probably many other progressive adjenda items ahead of giving the "poor" people money.
Who cares, he's outta here next time for darn sure, unless we put up another Palin cracker type. Not gonna get many "minorities" out to vote with that. Exactly how many "minorities" besides eskimos does Alaska have?
