The POTUS has no real power..
He's mearly a figurehead to parade before the masses.
There are others unknown [as yet] that wield the real power & play the role/roles of puppetmaster to the POTUS
..and the same statement applies to all major world leaders
Bush was a scapegoat. He wouldn't know which hand to wipe his backside with unless somebody told him [and reminded him to use loo roll]
