One of the reasons George W. Bush exasperates the Beltway Establishment is that he refuses to conform to the conventional wisdom. When the Beltway Mediacrats bray endlessly that you need to shuffle your staff, it is code for "hire some DC insiders to straighten out your problem." No doubt David Gergen stands at the ready. Lloyd Cutler and Clark Clifford can be disinterred. This Bush has refused to do.
But as the old saying goes, even a stopped clock is right twice a day. James Baker has long said that the chief of staff job burns you out after about two years. Andy Card has been there for 5 1/2 years, working from 5 am to about 9 pm every day. This tenure has been much longer than average. He probably should have stepped down after the 2004 election. Card gets good marks in a number of areas, less so in others, which, in the grand scheme of things, means that hes probably done a good job and deserves our gratitude. But it is long past time for him to move on.
But note that Bush is turning to an insider, Josh Bolton, as Cards replacement. Look for the Mediacrats to say "it isnt enough."
