Candidate filing deadline | Primary election | General election |

California uses a top-two primary system, in which all candidates appear on the same ballot. The top two vote-getters, regardless of party affiliation, move on to the general election. In states that do not use a top-two system, all parties are usually able to put forward a candidate for the general election if they choose to.[1][2]
Unlike the top-two format used in some states (Louisiana and Georgia special elections for example), a general election between the top-two candidates in California occurs regardless of whether the top candidate received 50% of the vote in the first round of elections.
As of June 2025, California was one of five states to use a top-two primary system, or a variation of the top-two system. See here for more information.

Submitted Biography: "I am a progressive democrat running for congress, and my life story is one of overcoming adversity and pushing past obstacles. I came to the United States from Ethiopia with my parents at the age of 11 in 2002. I was born with muscular dystrophy and a speech impediment, which made it challenging for me to communicate and navigate the world around me. Despite these challenges, I persevered and overcame all odds to become the person I am today. My mother worked tirelessly to raise me and my two sisters as a single parent, and I grew up as a middle child in a Christian Orthodox household. I graduated from Alief Hastings High School in Houston, Texas, in 2009, and went on to earn a degree in computer network systems from ITT Tech in 2011. Later, I received a Bachelor of Science in Technical Management from DeVry University in 2016. Throughout my career, I have worked as a Test Technician Level 5 at Hewlett-Packard, a Technology Support Analyst for NEXT Financial Group, and as a driver for Uber and Lyft. Currently, I am a Contract Disaster Housing Inspector for DHS FEMA, traveling to states affected by natural disasters such as Hurricane Harvey, Ian, and Nicole, just to name a few... I am passionate about helping people, and my experiences have taught me the value of hard work and perseverance. As a progressive democrat running for congress, I believe that everyone deserves a fair shot at success, and I am committed to fighting for policies that will make that a reality.."

Submitted Biography: "As Chairwoman of the Muwekma Ohlone Tribe of the San Francisco Bay Area, I work with governments at all levels on quality-of-life issues for my people. Public service and duty to our communities is something I learned from my mother and our Tribal elders. I am also a business owner and environmentalist. Fifteen years ago, I founded a California company that has partnerships in Mexico, Guatemala, El Salvador, and Honduras. We employ 6,000 people and divert 60 million pounds of clothing from landfills yearly. I am also the CEO of a California non-profit that teaches students and communities about sustainable practices and recycling education. Most importantly, I am a proud mother of Five, but I worry about my children’s futures as quality of life continues to dip for us while corporate giants become richer. Because of my work, I understand what's wrong with politics and I know how to fix it. Every crisis in our communities (unaffordable housing, homelessness, crime, gentrification, etc.) stems from the fact our politicians do not work for us and have no incentive to listen. I support term limits, age limits, and donation limits because I believe in putting people before politics. "

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.Partisan Voter Index
Heading into the 2024 elections, based on results from the 2020 and 2016 presidential elections, the Cook Partisan Voter Index for this district was D+21.
