W's
brain is the collection of neoconreps, Darth Vadar types, et. al. that President George W. Bush surrounds himself with since in the mind of some left-wing types he can't do any of his own thinking.
This is disturbing since W scored higher on an IQ
test than his last challenger John Kerry.
Karl Rove is considered the central processing unit of W's
brain, along with Dick Cheney and Condelezza Rice.
