2026 California House races master guide: All 52 districts on the November 3 ballot under Newsom's Prop 50 map

All 52 of California's seats in the U.S. House of Representatives are on the November 3, 2026 ballot, and this is the first general election held under the Prop 50 map.

Voters approved Proposition 50 on November 4, 2025, with 64.4% of the vote, the Secretary of State's Statement of Vote shows. The measure set aside the districts drawn by the independent Citizens Redistricting Commission and put the Legislature's map in their place for congressional elections through 2030.

The Secretary of State's certified list of candidates names two finalists in each district. Forty-nine of the state's 52 current House members are running. Four districts have no incumbent on the ballot, and nine match two candidates from the same party. In the 40th District, two sitting Republicans, Ken Calvert and Young Kim, are running against each other. California's delegation today is 43 Democrats, eight Republicans and one independent, according to the House Clerk's member list as of October 1.

The new lines changed the partisan math.

Under the commission's map, nine districts had more registered Republicans than Democrats in the Secretary of State's October 2025 report of registration. Under the Prop 50 map, four do in the October 19, 2026 report: the 5th, 20th, 23rd and 40th. By our count, those are also the only four districts where Republican candidates won a majority of the June 2 primary vote, in both the House race and the governor's race.

This guide lists every district's candidates, June results, registration and money in one table, then gives the 11 closest seats their own sections. Our voting master guide covers how and where to vote. Our candidates master guide covers the statewide races and the propositions master guide covers all 14 measures. For how the map came about, see our Prop 50 explainer.

The Prop 50 map replaced California's commission-drawn House districts for 2026:

Proposition 50 was a legislative constitutional amendment, Assembly Constitutional Amendment 8, which passed the state Senate 30–8 and the Assembly 57–20, according to the official voter guide for the November 2025 special election.

What, exactly, is Prop 50? Understanding California’s mid-decade redistricting measure

California voters have approved Proposition 50, authorizing a new congressional map that could add up to five Democratic-leaning seats ahead of the 2026 midterms. Here’s what the measure does and why it could reshape control of the U.S. House.

It adds a section to Article XXI of the California Constitution. The new districts are the ones drawn in Assembly Bill 604 of 2025, and the measure's text says they

"...shall temporarily be used for every congressional election for a term of office commencing on or after the date this subdivision becomes operative and before the certification of new congressional boundary lines drawn by the Citizens Redistricting Commission."

—Proposition 50, text of proposed law

The commission takes the job back in 2031, after the 2030 census. The Legislative Analyst noted that the total number of districts would not change and that most California districts "would change at least some" under the new maps. The Statewide Database at UC Berkeley publishes the AB 604 district boundaries used in the map below. Our Prop 50 results page has the measure's vote counts and the new district map.

Two special elections this year filled vacancies for the rest of the current term, and both were held in the old districts:

• 1st District: Gov. Gavin Newsom called the election after the death of Rep. Doug LaMalfa. Republican James Gallagher won outright in the June 2 special primary with 62.1% of the vote across 10 counties of the old district, the Secretary of State's official canvass shows. He was sworn in on June 10.
• 14th District: The vacancy followed Rep. Eric Swalwell's resignation. Democrat Aisha Wahab beat fellow Democrat Melissa Hernandez 53.1% to 46.9% in the August 18 special general election and was sworn in on September 2.

Gallagher and Wahab are both on the November ballot again, in the new 1st and 14th districts.

Registered Republicans outnumber Democrats in four districts under the Prop 50 map:

The Secretary of State counts registered voters by party in every district before each statewide election. Comparing the October 2025 report, the last before Prop 50 passed, with this October's report shows how far the map moved:

• Commission map, October 20, 2025: Republicans outnumbered Democrats in nine districts, the 1st, 3rd, 5th, 20th, 23rd, 40th, 41st, 47th and 48th, according to the registration by district.
• Prop 50 map, October 19, 2026: Republicans outnumber Democrats in four, the 5th, 20th, 23rd and 40th, the 2026 registration by district shows.
• Statewide, over the same year: Democrats went from 44.9% to 45.0% of registered voters and Republicans from 25.2% to 24.7%, by our math. The drop from nine districts to four reflects where the lines fall, not a statewide shift.

Between 18% and 31% of the registered voters in each district state no party preference, so registration is a guide to a district's lean rather than a count of votes.

California's top-two primary chose the two House finalists in each district:

California elects House members in a top-two system. Every candidate appears on one primary ballot, and only the top two vote-getters move on to the general election, whatever their party preference, the Secretary of State's primary elections page explains. The June 2 primary produced these November matchups:

• 42 districts with a Democrat against a Republican.
• 8 districts with two Democrats: the 4th, 7th, 11th, 12th, 14th, 29th, 34th and 37th.
• 1 district with two Republicans: the 40th.
• 1 district with a Democrat against a candidate with no party preference: the 6th.

Some June results were close enough to change the shape of a race. In the 40th, Democratic candidates won 43.0% of the vote combined, but five Democrats split it, and the leader among them, Esther Kim-Varet, finished third, 8,746 votes behind Kim. In the 4th, Democrat Eric Jones took second place from Republican Ray Riehle by 3,109 votes, 45,992 to 42,883, according to the June Statement of Vote.

Two challengers finished ahead of incumbents. Democrat Mai Vang out-polled Rep. Doris Matsui in the 7th, 65,617 votes to 61,114. Republican Jason Gibbs edged Rep. George Whitesides in the 27th by 544 votes, 62,758 to 62,214, although Democratic candidates there won 59.0% of the vote combined. In the 1st, Gallagher led McGuire by 854 votes.

The June electorate was much smaller than the last general election's. The primary drew 9,446,461 voters, 40.8% of those registered, according to the Secretary of State's participation statistics. The November 2024 general election drew 16,140,044, or 71.4%, the 2024 statistics show. June shares describe how each district's primary voters split. They are not a forecast for November.

Three measures of each California House district's lean, and the rule for the closest seats:

The table and the sections below use three measures, all from the Secretary of State:

1. The House primary vote: the combined share of all Democratic candidates and all Republican candidates in each district's June 2 House primary, from the Statement of Vote.
2. The governor primary vote: the same split for the June 2 governor's race inside each district, from the Supplement to the Statement of Vote. The governor's race had the same candidates in every district, so it works as a common yardstick.
3. Registration: each party's share of registered voters on October 19, from the report of registration by district.

We count a seat among the closest when the Democratic and Republican candidates finished within 15 points of each other on either of the two June measures. Same-party races are left out. Eleven seats qualify. The 25th, 23rd and 27th just miss. This describes June's vote. It does not rate or predict the races.

All 52 California House districts, candidates and June results:

The table lists every district with its counties, both finalists with their June share and money raised, the June party vote in the House and governor's races, and party registration. Money is each candidate's total receipts for 2025–26 through October 14, as reported to the Federal Election Commission. Incumbents running in a district with a new number are marked with the district they represent now.

California's 11 closest House races by the June primary vote:

These seats are in district order. Each section gives the June result, the party splits, registration and the money each candidate had raised through October 14, from the FEC's candidate totals.

California's 1st District pits state Sen. Mike McGuire against Rep. James Gallagher:

The new 1st runs from Sonoma, Lake and Mendocino counties east to Butte, Tehama, Glenn, Lassen, Plumas and Sierra, the Secretary of State's registration report shows. It no longer includes Shasta, Siskiyou, Modoc, Colusa, Sutter or Yuba, which were part of the old 1st that Gallagher won in June's special election.

In the regular June 2 primary for the new seat, Gallagher, whose ballot designation is "United States Representative/Farmer," took 42.1% (92,975 votes). McGuire, a "California State Senator," took 41.8% (92,121). Democrat Audrey Denney added 14.2%, so Democratic candidates won 56.8% combined to Republicans' 42.1%, according to the Statement of Vote. In the governor's race, the district split 56.5% Democratic to 42.1% Republican.

• Registration: 40.8% Democratic, 30.9% Republican, 19.2% no party preference. The old 1st had 17.9 points more Republicans than Democrats in October 2025.
• 2024: LaMalfa won the old 1st by 97,956 votes, the 2024 Statement of Vote shows.
• Money: McGuire had raised $2.27 million and had $153,647 in cash. Gallagher had raised $2.00 million and had $327,729.

Rep. Ami Bera is running in California's 3rd District against Republican Robb Tucker:

Bera represents the current 6th District, the House Clerk's member list shows. The new 3rd takes in all or part of El Dorado, Nevada, Placer and Sacramento counties. Under the commission's map, the 3rd was Kevin Kiley's district and ran along the Sierra Nevada as far as Inyo and Mono counties.

Bera led the June primary with 34.3% (76,653 votes). Tucker, a "County Supervisor/Businessman," was second with 29.9% (66,808). Democrat Heidi Hall took 12.8% and Republican Christine Bish 11.9%. Democrats won 55.7% combined and Republicans 43.2%, the Statement of Vote shows. The governor's race split 55.3% to 43.4%.

• Registration: 38.9% Democratic, 31.0% Republican, 21.1% no party preference. The old 3rd had 6.3 points more Republicans than Democrats in October 2025.
• Money: Bera had raised $1.49 million and had $1.65 million in cash. Tucker had raised $304,654 and had $16,451.

Rep. Kevin Kiley runs with no party preference in California's 6th District against Democrat Richard Pan:

Kiley won the old 3rd District as a Republican in 2024, 234,246 votes to 188,067, the 2024 Statement of Vote shows. The House Clerk now lists him as an independent, and the certified list shows him with no party preference and the designation "United States Representative." The new 6th takes in parts of Placer, Sacramento and Yolo counties.

Kiley finished first in June with 24.3% (47,165 votes), according to the Statement of Vote. Pan, a "Doctor/Health Advocate," was 2,157 votes behind with 23.2% (45,008). Republican Michael Stansfield took 20.1%, and Democrats Lauren Babb Tomlinson and Thien Ho took 12.3% and 10.7%. Because Kiley carries no party label, the House vote split by party overstates the gap. In the governor's race, the district went 56.4% Democratic to 42.2% Republican, a 14.2-point margin.

• Registration: 39.2% Democratic, 30.3% Republican, 21.9% no party preference.
• Money: Kiley had raised $3.72 million and had $34,648 in cash. Pan had raised $2.55 million and had $207,936.

Rep. Adam Gray faces Republican Kevin Lincoln in California's 13th District:

Gray won the old 13th in 2024 by 187 votes, 105,554 to 105,367, over Republican Rep. John Duarte. It was the closest House race in California that year, the 2024 Statement of Vote shows. Lincoln ran in the old 9th that year and lost to Rep. Josh Harder, 130,183 to 121,174. The new 13th takes in parts of Fresno, Madera, Merced, San Joaquin and Stanislaus counties.

Gray took 42.0% in June (41,086 votes) and Lincoln, a "Small Business Owner," 27.7% (27,157). Republican Vin Kruttiventi and Democrat Daniel Garibay Rodriguez each took about 15%. Democrats won 57.1% combined to Republicans' 42.9%, the Statement of Vote shows. The governor's race was closer, 54.5% to 43.7%. The 13th cast 97,897 votes in its House primary, the second-fewest of any district.

• Registration: 41.6% Democratic, 27.0% Republican, 23.6% no party preference. Gray's current district had 9.1 points more Democrats than Republicans in October 2025. The new 13th has 14.6.
• Money: Gray had raised $5.24 million and had $848,633 in cash. Lincoln had raised $2.97 million and had $448,388.

Rep. Jim Costa faces Republican Kyle Kirkland in California's 21st District:

Costa won the old 21st in 2024, 102,798 votes to 92,733, the 2024 Statement of Vote shows. The new 21st takes in parts of Fresno and Tulare counties.

Costa took 42.2% in June (43,461 votes) and Kirkland, an "Entrepreneur/Nonprofit CEO," 26.3% (27,076), the Statement of Vote shows. Republican Lorenzo Rios took 14.9%, Democrat Lourin Hubbard 10.3% and Democrat Eric Garcia 5.1%. Democrats won 57.6% combined to Republicans' 41.2%, a 16.4-point gap. The 21st makes the list on the governor's race, which split 56.4% to 41.7%, a 14.7-point gap.

• Registration: 40.9% Democratic, 26.8% Republican, 23.4% no party preference.
• Money: Costa had raised $1.69 million and had $500,767 in cash. Kirkland had raised $464,700 and had $13,101.

Valadao led in June with 40.7% (32,491 votes), the only Republican in the race, the Statement of Vote shows. Villegas, a "Teacher/Business Owner," took 32.4% (25,808), and Democrat Jasmeet Bains took 26.9%. That put Democrats at 59.3% combined. In the governor's race, the district split 56.4% to 41.6%, a 14.8-point gap. The 22nd cast 79,757 votes in its House primary, the fewest of any California district.

• Registration: 42.2% Democratic, 25.5% Republican, 24.3% no party preference. The old 22nd had 11.7 points more Democrats than Republicans in October 2025. The new 22nd has 16.7.

The new 42nd, which takes in parts of Los Angeles and Orange counties, has 10.8 points more.

Garcia took 56.5% in June (114,942 votes), the only Democrat in the race, the Statement of Vote shows.

Reps. Ken Calvert and Young Kim are running against each other in California's 40th District:

Calvert represents the current 41st and Kim the current 40th, the House Clerk's member list shows. The new 40th takes in parts of Orange and Riverside counties. Calvert led the June primary with 75,811 votes (34.9%) to Kim's 44,818 (20.6%), according to the Statement of Vote.

Kim had raised $10.15 million through October 14, the third-most of any California House candidate, and had $910,973 in cash. Calvert had raised $7.05 million and had $980,391. Registered Republicans outnumber Democrats in the 40th, 39.5% to 31.3%, the October 19 registration report shows.

The other seven same-party races, all between Democrats:

• 4th District: Rep. Mike Thompson (41.0% in June) faces Eric Jones (22.2%). Jones had raised $18.06 million, the most of any California House candidate, and $14.86 million of it came from Jones himself: $10.06 million in contributions and $4.8 million in loans, his FEC filings show.
• 7th District: Mai Vang, a "Teacher/City Councilmember," led Rep. Doris Matsui in June, 31.2% to 29.1%. Matsui's campaign had reported $7.84 million in receipts, including $5.4 million in loans from Matsui.

Four California House districts have no incumbent on the ballot:

Three members of the current delegation, Nancy Pelosi, Julia Brownley and Darrell Issa, did not run in June, the Statement of Vote shows. Rep. Linda Sánchez, who represents the current 38th, is running in the new 41st. That leaves four open seats:

• 11th District (San Francisco): Scott Wiener vs. Connie Chan, both Democrats (see above).
• 26th District (Los Angeles and Ventura counties): Democrat Jacqui Irwin, a "California State Assemblymember," took 41.3% in June, the Statement of Vote shows. Republican Sam Gallucci took 20.9%. Brownley represents the current 26th.
• 38th District (Los Angeles and Orange counties): Democrat Hilda Solis, a "County Supervisor," took 47.6% in June. Republican Pedro Antonio Casas, who has no FEC financial report on file, took 35.8%.
• 48th District (Riverside and San Diego counties): Jim Desmond vs. Marni von Wilpert (see above).

Four incumbents are running in a district with a different number than the one they represent now: Bera (6th to 3rd), Kiley (3rd to 6th), Sánchez (38th to 41st) and Calvert (41st to 40th).

California House candidates had raised $210.6 million through October 14:

The 104 finalists' campaign committees reported $210.6 million in total receipts for 2025–26 through October 14, by our sum of the FEC's candidate totals. That counts only the candidates' own committees. Spending by parties and outside groups is reported separately and is not included, and neither are contributions reported after October 14.

The five biggest fundraisers:

1. Eric Jones (D, 4th): $18.06 million, $14.86 million of it his own money.
2. Ro Khanna (D, 17th): $15.32 million. Khanna also had the most cash on hand of any House candidate on the ballot, $16.58 million.
3. Young Kim (R, 40th): $10.15 million.
4. Doris Matsui (D, 7th): $7.84 million, including $5.4 million in loans from Matsui.
5. Ken Calvert (R, 40th): $7.05 million.

Four of the five are in same-party races. At the other end, five finalists show no receipts in the FEC's records: Robin Littau (2nd), Jeff Frese (10th), Charles Hoelter (15th), Pedro Antonio Casas (38th) and Ricardo Cabrera (51st).

California's House results start at 8 p.m. on November 3 and take weeks to finish:

Polls close at 8 p.m. on Tuesday, November 3. Counties begin reporting results then and must send totals to the Secretary of State at least every two hours until the election-night count is done, the key dates page says. Mail ballots postmarked by Election Day count if they reach the county by November 10. Voters have until November 25 to fix a missing or mismatched signature.

Close House races in California can take that long to settle. In 2024, the two closest, the 13th and the 45th, were decided by 187 and 653 votes. Counties must certify their results by December 3, and the Secretary of State certifies the statewide results on December 11. Our voting master guide explains how the count works and why it takes weeks.

The winners take office at noon on January 3, 2027, when the Twentieth Amendment to the U.S. Constitution starts each new House term.
