Just a small thought on Jim Bunning.  This is why I do not favor term limits.  When someone has nothing to hold them accountable then they become very self centered.  Bunning is ticked at his party and fellow Ky Senator.  He then uses his very questionable principles to stop a highly popular bill because he has no one to answer to now that he is faced with a party imposed term limit.  There is no way he pulls this if he was running for reelection.
