And in retrospect, Palin’s stepping down from the stage (albeit temporary, what with her forthcoming literary homicide) represented exactly the kind of reversion that presidential politics requires going forward. Camp Obama seems to disagree, lobbing the president — the President of the United States — into desultory promos for George Lopez’s talk show and that torturous, rambling appearance a few weeks ago on Letterman, where the choir he spent forty minutes preaching to could barely stifle a yawn. In doing so they’ve made him overexposed jack-off material for the helpless left, the Megan Fox of the White House, a puny mortal whose deference to cool undercuts his duty to stir the shit in Congress and every other corner of the free world.
