Seriously, fascism is used once correctly for every 100 times it is used incorrectly. Bush was hardly fascist, no US Presidnt was.
Bush's economic policy was very nearly the definition of corporatism: providing State financial aid to select businesses to give them a heads-up on their competitors.
No American President has been fascist. Many of them, however, fit certain of the criteria. Bush was probably the closest.
He was indeed one of the closer ones, though he still wasn't close to being fascist.
