I am not convinced that Cain will attract a significantly larger perportion of the Black vote.
His major gains will be in the “Guilty White” vote, which he will completely neutralize.
Neutralizing the guilty white vote would be enough to win against 0bama.
Cain will get more black votes than will ever be polled because a lot of blacks will pull the Cain(a real full blooded American black man whose people were actually slaves)lever when they get behind the curtain
