This page is about California's 1st congressional district. You may be looking for California State Route 1.

California's 1st congressional district includes Del Norte, Humboldt, Lake, Mendocino and parts of Napa, Sonoma, and Yolo Counties. The current Representative for this district is Democrat Mike Thompson, who has represented the district since 1999.

Competitiveness

This district was once conservative in nature; it was dominated by the GOP and was represented for many years by Rep. Donald H. Clausen. The trend toward the Democrats started in the 1970s with the migration of many environmentally-minded people from the San Francisco Bay Area who wanted to experience their lifestyle in an more open setting. Today, areas in Humboldt County and Mendocino County are known for their artist villages and the production of marijuana crops.

The GOP last held the seat in 1998, but when GOP Rep. Frank Riggs decided to run for the United States Senate, he was replaced by long-time Assemblyman and state Sen. Mike Thompson. Redistricting in 2001 added Democratic-leaning areas of Yolo County.
