# California's 8th congressional district

California's 8th congressional district is a congressional district in the U.S. state of California. As of 2023, Democrat John Garamendi represents the district. Currently, the 8th district includes parts of the Bay Area counties of Contra Costa County and Solano County, including the cities of Vallejo, Fairfield, Richmond and parts of Martinez.

## Competitiveness

Before the 2011 redistricting, the 8th district was a Democratic stronghold. It gave John Kerry his best performance in California in 2004, backing the Democrat with 84.2% of the vote. Barack Obama continued on this trend in 2008 when he received 85.22% of the vote in the district while John McCain received 12.38%.
The 8th district from 2013-2023 was located in a politically conservative region of the state with a "Strongly Republican" Cook Partisan Voting Index of R+10. The Cook Political Report ranked it the 87th most Republican-leaning congressional district in the United States.
In the 2012 election, the first after the state's adoption of top-two primaries, the 8th district was one of only two in California where two Republicans faced each other in a runoff election. In 2018, it was the only such California district.
