Having read some more of Christopher Andersen's Barack and Michelle: Portrait of an American Marriage
online, I'll definitely buy it to read the whole thing. It's one of a genre of celebrity biographies where the rule is not scholarly exactitude but to tell an interesting story. Being interesting is the exact opposite of almost everything published in respectable outlets about Obama, in which the goal has been not scholarly exactitude either, but to make him as boring as possible. It seems pretty clear that Andersen followed a lot of my book in looking for interesting angles on Obama, and it pays off.
