tool     

One who lacks the mental capacity to know he is being used. A fool. A cretin. Characterized by low intelligence and/or self-esteem.

That tool doesn't even know she's just using him.

Ron Suskind's latest book, The One Percent Doctrine, sets forth, in embarrassing, painful detail the extent to which Bob Woodward was used as a propaganda tool by the Bush Administration.

The subject: Woodward's quickly crumbling claim that George Tenet told Bush and Cheney that the case for Iraq having weapons of mass destruction was a "slam dunk."
