"It's hard to think of another president who lived in such meta-insulation. His rigidly controlled environment allows no chance encounters with anyone who disagrees. He never has to defend himself to anyone, and that is cognitively injurious. He's a populist who never meets people - an ordinary guy who clears brush, and brush is the only thing he talks to. Mr. Bush hails Texas as a place where he can return to his roots. But is he mixing it up there with anyone besides Vulcans, Pioneers and Rangers?"
