Herman Cane is worth a look, but an admitted long shot. He can certainly electrify a crowd, his business background is a huge plus, he is common sense guy too, very approachable.
I like Cain very much. My sister is working to see him elected. The caveat is no government experience. Government is really different than business. It operates by consensus in a way that isn’t present in business.
The ideal candidate would be someone who moved from governance of a state, into a successful business or vice versa. They need to be just nominally conservative, not perfectly conservative.
The place were conservatism matters most is in Congress. It is at that level that we can set the agenda with a President that isn’t an enemy to American ideals, though he may be wishy washy otherwise.
