His administration *did* do that portion of the job well, but that's not all there is to the mission.
His inability to walk and chew gum at the same time WRT the War on Terror, controlling domestic spending, and simply *defending* himself from 'rat attacks set the stage for the disaster of a government we're saddled with today.
He had the opportunity to deal a serious blow to the left, but he decided to go along with them instead.
True enough. He made history in 2002 by increasing his majority in Congress in an off-year election--a rare feat. He won in 2004 by 3 million votes...then, from his second inaugural onward, he flaked out. Make of him what you will, he was a failure as a visionary, and that's what enabled the 'rats to eat his lunch for four long gut-wrenching years.
