Former U.S. Rep. Pat Toomey is the Republican nominee for Senate in Pennsylvania.

Toomey won the nomination over activist Peg Luksic.

Toomey lost the 2004 nomination to five-term Sen. Arlen Specter. But Specter switched to the Democratic Party last year after concluding he could not beat the more conservative Toomey again in a GOP primary.

The 48-year-old Toomey represented the Allentown area in Congress for six years after a career in the private sector working in finance and running restaurants. He went on to run the anti-tax group Club for Growth until last year.

Specter is facing U.S. Rep. Joe Sestak in the Democratic primary. Specter has held the seat since 1981 and is endorsed by the Democratic Party.
