These kind of books compete with novels for females readers, so they use a novelistic omniscient narrator and generally don't slow down to cite sources or to consider alternative explanations. To pick a minor but intriguing example, on p. 139 Andersen writes:
Determined to do something in public service, he resolved to return to Illinois and take the bar exam. He passed on the first try. (Michelle had failed on her first attempt but passed on the second.)
Now, that's what I surmised in VDARE.com in February 2008, although I presented the alternative possibility that she didn't even try to pass the bar exam (which in Illinois is pretty easy -- 81% passed the time Michelle passed) when the rest of her classmates took it:
One problem remained: the Illinois bar exam. It appears that in 1988 she either failed it or was unready even to try it. She eventually passed and was admitted to the bar in May 1989, almost a year after graduation. (In contrast, her husband was admitted only a half year after graduating from Harvard Law School three years later).
But, the question is open whether Andersen has a confidential source that has confirmed what I surmised from the public record, or whether he's merely passing on my inference in a streamlined, omniscient form. We can't tell from his notes.
