California's 1st congressional district


California's 1st congressional district is a congressional district in the U.S. state of California.
Doug LaMalfa, a Republican, has represented the district since January 2013.
Currently, the district encompasses the northeastern part of the state. It consists of:
Prior to redistricting by the California Citizens Redistricting Commission of 2011, the district encompassed much of the North Coast and Wine Country, as well as part of the Sacramento Valley. It consisted of Del Norte, Humboldt, Lake, Mendocino, and Napa counties plus portions of Sonoma and Yolo counties. That area is now primarily within the 2nd district, with the rest falling within the 5th and 3rd districts. The current district comprises much of the territory that had been the 2nd and 4th districts.

Competitiveness

Prior to 2013, the GOP last held the seat in 1998 when U.S. Representative Frank Riggs decided to run for the U.S. Senate. Riggs was replaced by long-time Democratic Assemblyman and State Senator Mike Thompson. Redistricting in 2001 added Democratic-leaning areas of Yolo County.
John Kerry won the district in 2004 presidential election with 59.7% of the vote. Barack Obama carried the district in 2008 presidential election with 65.60% of the vote. The new district is much more Republican-leaning; Mitt Romney and Donald Trump won the district by double digits in 2012 and 2016, respectively.
