California Rep. Gary G. Miller announced Wednesday he will not seek re-election.

“It has been a great honor to spend so many years in public service, striving to make a difference for Southern California families,” Miller said in a statement. “While there is still a lot of work to be done, it is now time for me to pass the baton.”

Miller, first elected in 1998, entered this cycle as the most vulnerable Republican. He represents a southern California district President Barack Obama carried with 57 percent of the vote in 2012.
