That’s an interesting idea I haven’t thought of. Running a credible DINO in the RAT primary will prevent them from crossing over and trying to affect ours.
Someone like Paul McHale comes to mind. He was Toomey’s predecessor and courageously voted for impeachment. Remember at the moment that the Dems don’t even have a serious candidate in the running. Jack Wagner, the State Auditor, is only a possible candidate. Running McHale would force the Dems to have to stay put in their own primary to vote for the establishment choice. If Specter does get the nod and McHale gets the Dem nod, it would prove an interesting general matchup.
