Sorry, azmagic, I really disagree to the point where I don't see that as possible at all. Herman Cain has never even held office before, or been a general, which is crucial in the modern age. That being said, he would have probably been a good candidate had he won the Senatorial primary back in 2004.
He's created jobs - something Obama has never done, as CEO of Godfather's Pizza. This is the Tea Party age NiK, lots can happen - like Johnson in Wisconsin. He is an excellent stump speaker, interviewer, and speech giver in general. He's witty and good for the party's image. He's also very conservative and would be an excellent contrast to Obama. In addition, he's not saddled with the baggage other GOP candidates have.
