Palin, writes Jonathan Raban in an excellent essay in the New York Review of Books, has an “exceptionally canny political instinct for connecting with her own kind.” It has been noted that her conservatism is resentment-based, and is fueled and nourished by the specter of elite mistreatment. (Palin is savvy enough to tease back.) But it is more than that. More than a list of grievances, Palin mixes Nixonian derision for those who think they know better with an aspirational dimension that motivates the middle class to vote. Out of the tony leagues of Washington and New York, she is — well, an Idahoan by birth, an exurbanite mother, able to expurgate the Republican Party of its own cosmopolitan tendencies. (This is one reason why the McCain campaign could not tend to her.) She is, as my friend @thetonylee says, “a hybrid of Nixon and Buchanan.”

The only presidential candidate who is able to put the boots to Obama and get away with it. What’s she running for? Not the question. What’s she running against? Not just Rockefeller Republicanism and the media, or pointy-headed law lecturer presidents, or Katie Couric: she wants to relitigate a bunch of issues that once were settled but now seem to be unraveling. The unrestricted embrace of immigration and the dilution of an American culture. Overweening Greenism. A complicated socially engineered tax code. A much larger role for government (embraced by the president who said that the era of Big Government Was Over and his successor, who was a Republican). The rule of experts. Even the concept of bipartisanship itself.
