Culture is politics. [Sarah] 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.
