Christopher Orr finds Palin's current maneuvers very odd:

The obvious, obvious play for her was to move to the center to reassure moderates that she wasn't her far-right caricature and reestablish some of the different-kind-of-Republican glow that once attracted reformist conservatives such as Reihan. Instead, she's been performing partisan panders so acrobatic they'd embarrass Mitt Romney--who, unlike Palin, actually needs to build credibility on the right. Whoever is advising her these days--assuming she's taking anyone's advice at all--is hammering early nails into the coffin of her future prospects.
