Add Mike Castle to the list of GOP primary losers who may go rogue and run as a write in candidate.

Politico:

Rep. Mike Castle is planning on polling a potential three-way Senate race to test his chances as a write-in candidate, a Delaware Republican tells POLITICO.

Castle, who lost his GOP primary by a 6-point margin to tea party upstart Christine O'Donnell nine days ago, opened the door to a potential write-in bid Wednesday evening when he told reporters off the House floor it was still a possibility he was considering.The GOP source did not have specifics on when Castle's team would conduct the poll, but viewed it as a practical step even if the nine-term congressman was unlikely to re-enter the race.

A spokeswoman for Castle, who put the chances of him running as a write-in "under 5 percent," said her boss likely wouldn't settle on a final decision before next week. According to the state Elections Commission, Castle would have to complete a form by next Thursday to officially qualify as a write-in candidate.

Said Castle spokeswoman Kate Dickens: "A lot of encouragement has come in, nice calls from people in Delaware who want an independent voice."

Unless the party starts punishing these sore losers by taking away their seniority and committee assignments, this spectacle will go on and spill over into 2012.

These guys are like Zombies who don't know they're dead. Their ego feeds on this notion that they are indispensable and desired by the electorate that just rejected them. In truth, they don't have a prayer and the entire thing is an exercise in vanity.
