The fact is, Rudy wants to be governor far more than just the JUNIOR Senator from N.Y. band he may even harbor a wish to become president. He isn't all that happy about Bloomy, so he might even think about being mayor again.

The Clintons rule the DNC because they bring in money, McAwful is their enforcer.
