Cabinet Exodus

The cabinet members are dropping like flies, and today Bush has tapped Bernard Kerik to be the new head of Homeland Security. Now, I do not know too much about Kerik, but most recently he has been in Baghdad helping to train the police force over there. Mission Accomplished! He is a close confidant of Rudy Guliani, which means...what? I'm not sure exactly, but seems like a little signal to me of Bush's preference for his successor.
