Post-filing deadline analysis
The following analysis covers all state legislative districts up for election in California in 2024. Information below was calculated on Feb. 28, 2024, and may differ from information shown in the table above due to candidate replacements and withdrawals after that time.
California had 58 contested state legislative primaries in 2024. This was the second-highest number and percentage of contested primaries since 2014.
All 58 contested primaries were top-two primaries where the top-two vote getters, regardless of party, advanced to the general election. This number was down from 60 in 2022.
Twenty-seven incumbents faced primary challenges, representing 41% of all incumbents running for re-election. This was lower than in 2022, 2020, and 2018 but higher than the 2016 and 2014 election cycles.
Of the 27 incumbents in contested primaries, 22 were Democrats and five were Republicans.
Overall, 328 candidates — 191 Democrats, 123 Republicans, and 14 from minor parties — filed to run. All 80 House and 20 of 40 Senate seats were up for election.
Thirty-four of those seats were open, meaning no incumbents filed. This guaranteed that at least 34% of seats up for election would be represented by newcomers in 2025.

Footnotes
- ↑ Ballotpedia defines an incumbent as retiring if the incumbent did not file for office or filed for office but withdrew, was disqualified, or otherwise left a race in a manner other than losing the primary, primary runoff, or convention. If an incumbent runs as a write-in candidate, Ballotpedia does not consider them to be retiring. If an incumbent runs in the same chamber for a different seat, Ballotpedia does not consider them to be retiring.

If the incumbent withdrew from or did not participate in the primary but later chose to seek re-election to his or her seat as a third party or independent candidate, the seat would not be counted as open. If the incumbent retired or ran for a different seat in the same chamber, his or her original seat would be counted as open unless another incumbent from the same chamber filed to run for that seat, in which case it would not be counted as open due to the presence of an incumbent.
