Newt just appeared on O’Reilly and answered every question directly and turned it completely around. No way can Romney do this. Newt will be able to attract enthusiastic support, while Mitt would get—at best—lukewarm support and no enthusiasm.
Mitt is simply a younger version of McCain. The GOP elites are more interested in being listened to than the future of this country. Gingrich doesn't listen to them and it annoys them greatly. Coulter, Barnes, Crystal, Will, et. al. are lazy. It's easier to find fault with an administration than to support one. It's also much more profitable.
