I've pointed this out before. But I trust Rasmussen to poll older white conservative voters who form the base of the GOP, if little else. And I presume their methods and samples are uniform. All of which is a roundabout way of saying that Rasmussen's latest poll of Obama against a generic Republican shows the generic dude – let's call him Bob Forehead (in honor of Stamaty) - with a 6 point lead.
But Rasmussen reveals at the same time that every GOP candidate but one fails to match Bob Forehead even before the shape of the general campaign next year gels. That one is not Romney. Rasmussen's latest poll of Obama vs Romney reveals that Obama would beat Romney by six points. So that's a 12 point gap in a conservative-skewed sample between Forehead and Romney. In contrast, Rasmussen now has Gingrich 2 points ahead of Obama.
Romney underperforms Forehead by 12 points, Gingrich by only four, in the polling group likeliest to capture the most GOP-friendly sample. Romney is losing his electability card. Which is one of the very few cards he has with the base of his own party.
