So he loses re-nomination, he's going to go home and sulk and force everyone to pay for a special election, rather than man up and serve out the last few months of his term with dignity.
I'm getting really tired of this BS from politicians who cut and run before their term is over. We really need some kind of law to punish them for resigning early for reasons other than emergencies (e.g. suffered major stroke and is unable to carry out his duties). These unnecesary special elections cause all kinds of problems (remember when Hastert gave Oberweis his blessing to succeed him and he managed to lose a safe GOP seat to an then unknown RAT?) Perhaps its needed even moreso than term limit laws.
