(CNN) - Former Rep. Richard Pombo, R-California, will announce Tuesday that he is running again for the House, two GOP sources confirm to CNN.
Pombo was elected in 1992, but lost his seat in 2006 to Democrat Jerry McNerney. But Pombo is not looking for a rematch against McNerney - instead, he's running to succeed retiring GOP Rep. George Radanovich, who represents a neighboring congressional district.
Radanovich, who was elected in 1994 and ran unopposed in 2008, has endorsed state Sen. Jeff Denham to replace him. Former Fresno Mayor Jim Patterson has also announced his plans to run for the GOP nomination.
