Chris Albritton gives about as good a summation of the Bush administration as I’ve ever read:
When faced with choosing between secrecy and openness, stubbornness and a willingness to get things done, the Bush people will always choose the secret, stubborn path — even if the easy thing to do is also the right thing to do. If they can’t turn back the clock and undo the torture at Abu Ghraib, then by all means come clean and get it out of the way. When faced with the kidnapping of an American civilian, they could get her out by either speeding up prisoner releases or at least not impeding it. They were going to happen anyway! In both cases, doing the right thing is, well, the right thing to do and it’s good politics.
But that’s too complicated for these guys.
