When I heard Carville blather on the other day about starting a new party, it signaled a level of desperation and fear, because the ship the Leftists were sailing on has been inundated with even more Verminous Rats (who have even fewer principles and are more openly vicious then Carville and his buddies on the Left are, as hard as that is to believe) so in order to survive, they want to jump into the water and leave the ship to the tender mercies of the New and More Vicious Rats.
They are dangerous, but I do enjoy seeing it!
