Did the Clinton Camp leak book in order to kill it?

Probably.

In my opinion it is probably the most honest thing that wretched woman has ever done.

Ben Smith of The Politico describes it well enough for most. http://www.politico.com/news/stories/0507/4198.html There is nothing that happens around Hillary Clinton that happens by surprise, she never stops manipulating the world around her. But, I don't think she can disguise the truth forever. American people are smarter than she gives them credit for, they will be informed when necessary.
