The Hottest Super Tuesday Congressional Primaries in California

Of state’s 10 most-contested 2024 congressional races, seven are for GOP-held seats, including five in districts Biden won in 2022, with four rated as toss-ups.

California Republicans flipped two House seats and defied the odds by defending several others during the 2022 midterms, helping the GOP regain a narrow House majority that is at stake in 2024.

Replicating that success may be difficult in November, as defeating seven of California’s 11 Republican House incumbents is a top national focus for Democrats in 2024, especially the six who were victorious in the 2022 elections in congressional districts won in 2020 by President Joe Biden.
