Cain Nomination:
If Herman Cain is nominated, it will be a seismic shift in voter demographics. Gone for ever will be the solid 95% black vote the Democrats depend on, gone for ever will be talking points of liberals that Republicans are racists, and even better, we will have nominated the most conservative candidate who is not a life long politician and has no political baggage, is likable, has actually run a business successfully. Not a perfect candidate, but significantly better than others.
Don't bet on it. My entire family is black, and they all vote liberal Democrat. Not a single one of them is going to vote for Cain because he looks like them. On the contrary, they're going to view him as a 'traitor' to his race - a 'sell-out' to the 'racist, bigoted Republicans'.
Sorry, but that is true level of their indoctrination, and it's as solid as a rock.
