Even by the standard of politicians, this is a woman with an outsized ego. Combine that with her performance skills and an insatiable hunger for the limelight, and you can see why she will not stay in Wasilla now that she’s seen 30 Rock. The question journalists repeatedly asked last week — What are Palin’s plans for 2012? — is a red herring. Palin has no obligation to answer it. She is the pit bull in the china shop of American politics, and she can do what she wants, on her own timeline, all the while raking in the big bucks she couldn’t as a sitting governor. No one, least of all her own political party, can control her…

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.
