California 31st Congressional District — U.S. House

November 3, 2026 General Election — Cisneros (D) vs. Ching (R)

District: CA-31 spans the eastern San Gabriel Valley into southwestern San Bernardino County — including Pomona, West Covina, Azusa, El Monte, and communities out to Chino. Heavily Latino and Asian American; voter registration is solidly Democratic (roughly 48% Dem / 21% GOP), making this a safe-to-likely Democratic seat. Incumbent: Gil Cisneros (D), first elected here in 2022, is seeking a third term. California's top-two primary sent Cisneros and Republican Eric Ching to the November runoff. A Democratic hold would matter to the national House math (Democrats need a net gain of six seats to flip the chamber).
Judges on your ballot: CA-31 spans two appellate districts, so the judges on your ballot depend on your county: Los Angeles County voters see the 2nd District’s 18 Court of Appeal questions →. San Bernardino County voters (Chino, Ontario) see the 4th District’s 15 questions →. Everyone also votes on the 2 Supreme Court justices, shown at the top of each page.
Also on your ballot: CA-31's San Bernardino County communities (Chino, Chino Hills, Ontario, Montclair) also help elect a State Senator — District 32 (Seyarto vs. Tate) — and choose countywide offices: Auditor-Controller-Treasurer-Tax Collector, Sheriff, Superintendent of Schools, and Board of Supervisors District 4 →

Top Issues / Platform

  • Veterans: expand veterans' benefits, housing, and family support
  • Education: make college more affordable, first-generation student support

  • Public safety & jobs: community policing, manufacturing and good union jobs

Read on the race

  • Strengths: Incumbent in a D+ district with strong name ID and a personal story that resonates locally; institutional support (House Dems, labor, veterans groups).
  • Weaknesses: the district's Asian American and NPP voters can split tickets; Republicans target him by linking him to national Democratic issues on crime and the border.
  • No celebrity or self-funded opponent means outspending is unlikely — race is rated safe/likely Democratic.

Read on the race

  • Strengths: A clean check on an incumbent in a year when affordability frustrations are running high (PPIC shows affordability as the top voter concern).
