Rep. Joe Sestak (D-Pa.) will not run for Senate in 2010, according to a statement from his office Thursday.

“Congressman Sestak is honored to be rehired to represent the 7th Congressional District of Pennsylvania,” his communications director Jonathan Dworkin said. “His absolute focus at present is addressing the nation’s pressing economic crisis, and bringing unprecedented accountability transparency and bi-partisanship to the 111th Congress … and to future Congresses in the House of Representatives.”

Sestak, who is flush with cash despite his junior status in the state’s delegation, was discussed as a possible candidate against Sen. Arlen Specter (R-Pa.) in 2010, though never publically talked about a bid. In the middle of October, Sestak reported having $3.1 million in his campaign account.
