Patrick Joseph "Pat" Toomey (born November 17, 1961) is a United States politician; he is currently a Republican member of the House of Representatives from Pennsylvania. He has represented the 15th Congressional district since 1999, but has announced plans to retire in January 2005, at the end of his last Congressional term.
Toomey was incumbent Arlen Specter's Republican challenger in the 2004 Senatorial primary. He criticized Specter as a spendthrift in the somewhat conservative Republican party of Pennsylvania, and narrowly lost to the incumbent. Toomey's campaign theme was that Specter, a moderate-to-liberal figure, was not conservative enough to be the Republican nominee.
