"I think McCain also entertains (or entertainED) those thoughts. But you are CERTAINLY right: if the margin is 3-4, there will be STRONG incentive for Breaux and Miller to jump. STRONG incentive."
Yep...the incentive will be to enhance their political viability in the future and the JUSTIFICATION will be the unwillingness of RATS to hold folks like DNC Chairman Terry McAuliffe and Torricelli accountable for their criminal acts.
FReegards...MUD
