I think Bush has had that book for a LONG time. I've heard that he used it for business strategery in Texas long before he became governor. That is a book that is owned by many CEOs.
Of course, the DemocRATS want to promote the idea that Bush is too stupid to read books like "The Art of War", and is letting others do his thinking for him.
Those are the ones described here:
mis·un·der·es·ti·mate:
1: to estimate a person's intelligence as being dramatically less than its actual level.
2: to insist that a person who repeatedly hands you your ass is too stupid to be able to do so.
Hahahaha
