I don't trust the pollster in general elections, since its sample is so skewed toward white, older, Republican voters. But that's also why Rasmussen is a good way to look inside the GOP base. Right now, just when you would think Republicans would be rallying behind their likeliest nominee, Romney, they remain deeply ambivalent about him. In fact, the latest data shows Obama taking hs first daylight lead over Romney in Rasmussen's polling since the summer: by 6 points.
Against a generic GOP candidate, Rasmussen finds Obama behind by 3 points. So Romney is underpolling a generic Republican by nine points, according to Rasmussen. Ditto with Gingrich. Cain is behind by 10 in Rasmussen, while Huntsman, surprisingly, does almost as well against Obama as Romney and Gingrich.
