Bush could have started a real clean sweep as soon as he got into office. He didn't. The people he picked for his cabinet are pissants, look at them. Colin Powell is a UN buttboy, a socialist. Ashcroft is a Reno clone. Whitman is a utopian socialist, just as Norton is. Bush even created a new cabinet position and put Tom Ridge in it. Ridge could get elected running on the democrat ticket anywhere.
Face it, if he's picking such losers for his cabinet, then how is he ever going to get any good advice on who to get rid of? Look at who he picked to head the FBI. I don't expect anything like a cleanup.
