The Noonan column has been overtaken by events. After the Brit Hume interview, there’s no reason whatever to think that Cheney will be replaced. In the first place, he can’t be REPLACED. He was actually elected. That means he leaves only if he resigns or is impeached. And something tells me he isn’t going to end his career in ignominy if he can help it. Which is why he wised up and went on TV yesterday.
