She may have retired from office, but Sarah Palin is back in the political saddle, hitting the campaign trail for Republicans in Texas, Arizona, and Minnesota, according to a statement released on her Facebook page Wednesday. In characteristic fashion, she's promised to campaign "FOR the people and AGAINST politics as usual," although she will be supporting incumbents Rep. Michele Bachmann in Minnesota and former running mate Sen. John McCain, who faces a right-wing challenge in Arizona. Palin will also help defend Texas Gov. Rick Perry against a primary challenge from Sen. Kay Bailey Hutchinson. According to Politico writer Ben Smith, Palin's announcement suggests that "she isn't content to merely be a media figure with her new Fox News contract, but intends to be active in shaping the Republican Party."
