All US House seats to be contested in 2020
California has 53 congressional districts, easily the most in the nation. Democrats dominate the delegation, holding 45 seats after flipping 7 in the 2018 midterms. There are two vacancies.

2020 will be the final election with this map, as redistricting will occur in 2021 after the 2020 Census. California is expected to lose a congressional district which would be the first time this has happened in the state's history. The new district boundaries will be first contested in the 2022 election.
