I don't recommend reading the Washington Post's Angler series on Vice President Cheney before bedtime. It certainly gave me nightmares. I can't think of another high American official who has pursued policies so deeply subversive of the Constitution and the law. Because Cheney combined enormous influence with nearly total unaccountability, he has dominated every aspect of Bush administration policy. Because he combines great secrecy with abominable judgement, those policies have catastrophically failed.
Bush bears a huge burden of guilt for outsourcing so much of his Presidency to this man. Fortunately for him, he is too dumb to know it.
