U.S. House

California 13th Congressional District — 2026

California’s 13th District (San Joaquin Valley) elects a U.S. representative on November 3, 2026. Democratic incumbent Adam Gray and Republican Kevin Lincoln II advanced from the June 2 top-two primary.

What this office is

Each U.S. House district elects one representative for a two-year term. Your district is assigned by official maps and your registered address — not by opening a page on this site. The House originates revenue bills, shares lawmaking with the Senate, and can impeach federal officers. All 435 voting seats are on the ballot in 2026. California’s top-two primary can send two candidates of the same party to November; in 2026 this district advanced one Democrat and one Republican.

Why it matters in 2026

Gray flipped the seat in 2024. Ballotpedia included CA-13 on its 2026 House battlegrounds list. County elections officials assign the district on your mail ballot.

Primary percentages: Gray 42.0%, Lincoln 27.7%, with two other candidates eliminated, per Ballotpedia’s certified table.
