What is something that has been a struggle in your life?

Mark DeSaulnier (D)

Thirty-five years ago, I found out that my father, a World War II veteran who served his country proudly, took his own life with a firearm. This experience taught me that we need to do more to help people who may not seek help. Suicide is the 11th leading cause of death in the United States. That’s why I introduced the Suicide Prevention Assistance Act to integrate mental health screenings as an essential part of primary of primary care visits.

What qualities does the U.S. House of Representatives possess that makes it unique as an institution?

The House of Representatives is unique because it is directly accountable to the people.

Post-filing deadline analysis

The following analysis covers all U.S. House districts up for election in California in 2024. Information below was calculated on 1/16/2024, and may differ from information shown in the table above due to candidate replacements and withdrawals after that time.

Two-hundred forty-one candidates filed to run for California's 52 U.S. House districts in 2024, including 125 Democrats, 88 Republicans, and 28 independent or minor party candidates. That’s 4.63 candidates per district. In 2022, the first election after the number of congressional districts in California decreased from 53 to 52 following the 2020 census, 5.2 candidates filed per district. In 2020, when the state still had 53 Congressional districts, 4.94 candidates filed per district. In 2018, 4.6 candidates filed.

The 241 candidates who ran in California in 2024 were the fewest total number of candidates since 2016, when 202 candidates ran. Forty-five incumbents—34 Democrats and 11 Republicans—ran for re-election. That was fewer than in 2022, when 47 incumbents ran. Six districts were open, one more than in 2022, and the most since 2014, when six districts were also open.

Incumbents Barbara Lee (D-12th), Adam Schiff (D-30th), and Katie Porter (D-47th) ran for the state’s open U.S. Senate seat. Incumbent Sen. Laphonza Butler (D) didn't run for re-election. Incumbents Grace Napolitano (D-31st), Tony Cárdenas (D-29th), and Anna Eshoo (D-16th) retired from public office. One incumbent—Rep. Kevin McCarthy (R-20th)—left Congress before the end of his term. A special election was held to fill his seat before the general election.

Fifteen candidates—12 Democrats, two Republicans, and one nonpartisan—ran in the open 30th district, the most candidates running for a seat in 2024.

Forty-two primaries were contested, the fewest since 2018, when 41 were contested. All 52 primaries were contested in 2022, and 47 were in 2020. In California, which uses a top-two primary system, a primary is contested if more than two candidates file to run.

Incumbents ran in 35 of the 42 contested primaries. That’s lower than 2022, when 47 incumbents ran in contested primaries, but higher than every other year since 2014. In 2020, 32 incumbents faced contested primaries. Thirty-nine incumbents did so in 2018, 36 in 2016, and 32 in 2014.

Democratic candidates ran in every district. Republican candidates ran in every district except one—the 37th. Two Democrats, including incumbent Sydney Kamlage-Dove, one nonpartisan candidate, and one Peace and Freedom Party member ran in that district.
