Kerry figures that:
1.) diehard Dims don't care and "anybody but Bush"
2.) most of the "undecided" are that way because they don't read non-fiction and get all their info from the lamestream,
which is loathe to report negatively on anything from the left.
3.) and CBS's 60 Minutes isn't going to notice an anti-Kerry book, unless the Clintons sanction it.
A chapter in one of Hugh Hewitt's books discusses the fact that atheists and angry people don't read books.
