I think your right about his book being a poor seller (unless he tells all about his sexcapades in the Oral Orifice). But I think he will be upset if it doesnt become a best seller.
You have to remember that this guy has a very fragile ego and is easily offended.
He will take it as a rejection if the book doesnt do well.
Hopefully he will become so despondent when his book only sells 100 copies that he kills himself with a stolen handgun.
Little else the Klintoons do is newsworthy.
