...but no cigar
I'd say you'll need to buy the book. Somehow I suspect that the most thumbed chapter will be about his affair will be, well, thumbed, read and put back on the shelf. Most of the details I suspect will be in other chapters. According to this interview, while Clinton has a lot of friends, but this is an election year in a very partisan year. His enemies (or rather the allies of Bush) are probably hoping to tar him by remote, and that the tar gets spread around.
Personally, I'll wait for the highlights in the press, and the paperback. I've read the first book.The movie already came out. Actually two movies so far.
