Actually, it's a pretty devastating piece. Hurrah for Michael Joseph Gross.
I tried to pick out a couple of excerpts, but there's just too much good stuff. So let's just have this last paragraph of the intro:
This spring and summer I traveled to Alaska and followed Palin’s road show through four midwestern states, speaking with whomever I could induce to talk under whatever conditions of anonymity they imposed—political strategists, longtime Palin friends and political associates, hotel staff, shopkeepers and hairstylists, and high-school friends of the Palin children. There’s a long and detailed version of what they had to say, but there’s also a short and simple one: anywhere you peel back the skin of Sarah Palin’s life, a sad and moldering strangeness lies beneath.
