It appears increasingly likely that Toomey will be the GOP’s standard-bearer next year in the race for the seat currently held by party-switching Sen. Arlen Specter (D). Specter defected from the GOP earlier this year because his prospects for beating Toomey in the primary were dim. “I am honored to have Congressman Pitts’ support and I look forward to him playing an important role in my campaign,— Toomey said in a statement. After Specter’s switch, national Republican operatives were openly looking to recruit another candidate besides Toomey, who many viewed as too conservative to win the general election in a Democratic-leaning state.
