It's happening:
http://www.cnn.com/2009/POLITICS/02/10/stimulus.gop.pac/index.html An influential conservative political action committee is pledging to support primary challenges to any Republican senator who backs the economic stimulus package -- the latest public show of dissatisfaction from the right over the massive measure before Congress.
The PAC's pledge appears most threatening to Specter, the only one of the three who faces re-election in 2010. A longtime moderate, Specter has faced tough primary challengers in the past, including Club for Growth President Pat Toomey in 2004.
"[Sen. Specter] crossed the line one too many times," Wheeler told CNN. "We're now going to get involved in finding a conservative alternative."
Toomey has said he is not interested in running again, and another credible challenger has yet to emerge in the race. Still, Specter's decision to vote for the stimulus bill has irked many Republicans in his home state and may have virtually guaranteed a primary fight.
Speaking to CNN Tuesday, Specter said his vote has resulted in a flood of negative phone calls to his office and predicted it would lead to a tough primary battle.
