And what WILL she say the "next time," because as sure as you and I are breathing, you know there WILL be another time.
Book sales were the least of the reasons this book was written for. This book is for "political innoculation" or "strategic campaign innoculation".
In other words, in several years, when she runs for president, and people ask her questions, like Monica, or whitewater or whatever, she can say or more accuratley she gets to say "I've already addressed that", or "I talked about it in my book", "its old news", "thats already been discussed at lenght".
This is actually pretty standard for both political parties and is done in a variety of ways. Her writing a book is probably one of the better strategy moves.
This book was never about money, it was about her testing the waters for the future, and getting a future campaign distraction out of the way, so as to make anyone who brings up her past sound like they are "beating a dead horse". The media will happily say that over and over again.
