After the Palin-McCain ticket lost, conservative pundits admonished her to start studying the issues. If “Going Rogue” and its promotional interviews are any indication, she has ignored their entreaties during her months at liberty. Last week, Greta Van Susteren chastised Oprah for not asking Palin “one policy question,” but when Barbara Walters did ask some, Palin either recycled Dick Cheney verbatim (Obama is “dithering”) or ran aground. Her argument for why “Jewish settlements” should be expanded on the West Bank was that “more and more Jewish people will be flocking to Israel in the days and weeks and months ahead.” It was unclear what she was talking about  unless it was the “rapture” theology that requires the mass return of Jews to settle the Holy Land as a precondition for the return of Christ.

The discredited neocon hacks who have latched on to Palin as a potential ticket back into power have their work cut out for them. But it’s better for Palin’s purposes to remain as blank a slate as possible anyway. Some of her most ardent supporters realize that she’ll drive still more independent voters away if she fills in too many details. And so Matthew Continetti, the author of the just-published “Persecution of Sarah Palin” and her most persistent cheerleader after William Kristol, wrote in The Wall Street Journal that her role model for 2012 should be Bob McDonnell, the new Republican governor-elect of Virginia, who won on “a bipartisan, center-right approach.”

What Continetti means is that Palin could still somehow fudge her history as McDonnell did; his campaign kept his career-long history as a political acolyte and financial beneficiary of Pat Robertson on the down-low. Even the far right has figured out that homophobia is a turnoff to swing voters, which is why Palin goes out of her way in “Going Rogue” to remind us she has her very own lesbian friend. (What’s left unsaid is that the book’s credited ghost writer, Lynn Vincent, labeled homosexuality as “deviance” in her own writings for World, the evangelical magazine.)

But no matter how much Palin tries to pass for “center-right,” she’s unlikely to fool that vast pool of voters left, right and center who have already written her off as unqualified for the White House. The G.O.P. establishment knows this, and is frightened. The demographic that Palin attracts is in decline; there’s no way the math of her fan base adds up to an Electoral College victory.

Yet among Republicans she still ties Mitt Romney in the latest USA Today/Gallup survey, with 65 percent giving her serious presidential consideration, just behind the 71 for her evangelical rival, Mike Huckabee. The crowds lining up in the cold for her book tour are likely to be the most motivated to line up at the polls in G.O.P. primaries. They don’t speak the same language as Romney, Tim Pawlenty, Michael Steele, Mitch McConnell, John Boehner or, for that matter, McCain. They are more likely to heed Palin salesmen like Glenn Beck and Rush Limbaugh than baffled Bush administration grandees like Peter Wehner, who last week called Palin “a cultural figure much more than a political one” on the Web site of the establishment conservative organ Commentary.

Culture is politics. Palin is at the red-hot center of age-old American resentments that have boiled up both from the ascent of our first black president and from the intractability of the Great Recession for those Americans who haven’t benefited from bailouts. As Palin thrives on the ire of the left, so she does from the disdain of Republican leaders who, with a condescension rivaling the sexism they decry in liberals, belittle her as a lightweight or instruct her to eat think-tank spinach.

The only person who can derail Palin is Palin herself. Should she not self-destruct, she will doom G.O.P. hopes of a 2012 comeback. But the rest of the country cannot rest easy. The rage out there is larger than Palin and defies partisan labeling. Her ever-present booster Continetti, writing in The Weekly Standard, suggested that she recast the century-old populist outrage of William Jennings Bryan by adopting the message “You shall not crucify mankind upon the cross of Goldman Sachs.” If Obama can’t tamp down that rage across the political map, Palin will at the very least pave the way for a demagogue with less baggage to pick up her torch.
