Well, I never really understood why Gingrich has this lopsided negative favorable ratings. he certainly comes over as much more competent and likeable southern granddad-like than for example a shrill Michele Bachmann or a dull cowboyish Rick Perry. In the unlikely event that I were a Republican, I could imagine myself voting for either Paul or Gingrich ...
The only path to Gingrich winning would probably be if he had a real strong showing in the SC-GA-FL trifecta. But for this Gingrich needs to count on A) Cain dropping out after New Hampshire or even Iowa and B) Perry continuing getting hammered in the debates or saying something stupid. That would give him the boost needed in these 3 "home" states. The media spin could do the rest for him, like it did for McCain after NH. If he does well in the 3 states, but the media is not behind him, I don't see how he can win the nomination, because simply he does not have the money to compete after these 3 states.
