That's the explosive story being put out by Ron Suskind, author of a new book on the war on terror called The One Percent Doctrine. (You can see Suskind discussing with Wolf Blitzer this and other revelations from the book here.)
Why would Bin Laden want Bush to win in 2004, and to that end, why would he release his inflammatory tape the weekend before the election? Simple. Bush has been the greatest recruiting tool imaginable for Bin Laden. Bush's sheer ham-fisted incompetence, his couching of the war in terms that make it sound like a Christian crusade, and his disastrous decision to invade Iraq have all enormously assisted Al Qaeda. Based on his private sources, Suskind is confident in asserting, therefore, that the CIA concluded in 2004 that Bin Laden was supporting Bush.
I've said it before, and I'll say it again: W--Bin Laden's favorite enemy.
