So that's where his concepts come from!
From yeseterday's Washington Briefing (WaPo, Dan Froomkin):
Judging from the blistering analyses in Time, Newsweek, and elsewhere these past few days, it turns out that Bush is in fact fidgety, cold and snappish in private. He yells at those who dare give him bad news and is therefore not surprisingly surrounded by an echo chamber of terrified sycophants. He is slow to comprehend concepts that don't emerge from his gut. He is uncomprehending of the speeches that he is given to read. And oh yes, one of his most significant legacies -- the immense post-Sept. 11 reorganization of the federal government which created the Homeland Security Department -- has failed a big test. [my emphasis]Understanding Bush's thinking is a problem in gastroenterology. Makes sense.
