Dunn paints a disturbing portrait, based on extensive interviews and research, of Palin as a pathological liar. He quotes her own press releases, Facebook and Twitter posts, and memoir to show how she distorts and denies facts (such as declaring her relief at being cleared of any ethics violations in regard to "Troopergate," in response to the bipartisan investigating committee's announcement that she had committed ethical violations by abusing the power of her office). Because I follow several anti-Palin blogs, much of the information in the book wasn't new to me, although Dunn pulls everything together cohesively and provides extensive context and background. And he fleshes out some scandals to which I'd seen many allusions online but of which I'd been unable to find details.
Especially telling is Dunn's account of the 2008 Presidential campaign, which Palin seems to have assumed, rightfully or not, was all about her rather than John McCain. I haven't yet read Game Change
A final note: Palin, in her nauseatingly oft-repeated meme about being a victim of the "lamestream media," whines about the scrutiny of her children. Without subjecting them to further undue scrutiny, Dunn shows just how much she has contributed to the media interest in her kids by constantly referring to them in ways other candidates and political figures didn't and don't. He contrasts McCain and Biden, who both had sons in the Armed Forces, with Palin, who uses her son's military record as a credential. (She now refers to him as a "combat vet" even though his discharge papers show that in Iraq, his job was driving top officials around--he never saw combat.)
This is, as I've said, an excellent read, but I had to take it in small doses. It's discouraging that by uttering a few catch phrases and palling around with Franklin Graham (Billy Graham's son and the CEO of Samaritan's Purse, who draws a million-dollar annual salary from the "charity"), a charlatan like this woman can stir up the religious right, even though there's so little evidence that Christianity is anything more to her than a buzzword to garner votes.
