Cain is far, far superior to Keyes.
Cain couldn't even beat a RINO in a lousy state election and you believe that he can win the primaries, as the "VOTE FOR ME, I'M BLACK, BUT I'M NOT OBAMA, EVEN THOUGH I DON'T KNOW THE FIRST THING ABOUT HOW TO WIN AND ELECTION" ?
Herman is what...65, 66? He's a black conservative, he's managed to survive two cancer bouts ( though NOT long enough to prove that it won't come back ), and he's NEVER won an elected office and PLEASE don't tell me that that doesn't matter. Nobody knows what kind of skeletons might be in his closet, because nobody knows all that much about him. The MSM will destroy him faster than you can blink once.
He seems like a nice man, I do believe, until proven otherwise, that he is a conservative, but he is NOT presidential material at all.
The first thing the lefties will do is turn him into an old, doddering "Uncle Tom". That is, of course, despicable, but it is what they do. And nobody knows how he will take that kind of abuse.
