The books are just a way for media companies to get payola to politicians via “advances “.
The payola game worked up until the last decade....when you could self-publish. Before that....the companies had a vast amount of control and could make large profits off some writers. I think it’s difficult now to hand out the payola and still survive as a major book company. Lets be honest, if it wasn’t for public libraries ordering vast numbers of Hillary’s last book....you wouldn’t have really noticed much on sales. When you go and ask about check-out statistics....it’s mostly on the shelf....not in someone’s possession.
