Palin has stood up to corruption, blowing the whistle on unethical behavior by the chairman of the Alaska Republican Party despite taking a lot of heat for it. But she's also gotten into some trouble of her own, and it almost seems that she fell into her anti-corruption role by accident.
A description of Palin from her fellow Wasilla, Alaska resident Anne Kilkenny is well worth reading. (Kilkenny is also quoted regarding Palin in this New York Times story.) For further perspective, here's another close-up view of Palin as she's seen in Alaska.
UPDATE (September 4, 2008): As governor of Alaska, Palin asked for $550 million in earmarks in her first year in office, and for 31 federal earmarks totaling $198 million so far this year. Oink!
John McCain has long been a critic of earmarks. Turns out he has specifically been critical of earmarks requested by Sarah Palin.
