In this photo taken Sept. 7, 2012, California Rep. candidate Eric Swalwell gestures during an interview before an Alameda County Democratic Lawyers Club endorsement meeting at Everett &amp; Jones Barbeque in Oakland, Calif. Rep. Pete Stark, D-Calif. is used to coasting to re-election in the liberal enclave of the San Francisco Bay area he has represented since the end of the Vietnam War. Legislative gerrymandering kept him in a heavily Democratic district, and California's primary system virtually ensured that he would emerge to face Republican or fringe-party challengers with almost no chance of beating him in November. All that has changed this year, as Californians deal with two major political reforms that are remaking the congressional landscape and creating competitive races for the first time in many years.
