Sydney Kamlager-Dove, the Democratic incumbent first elected in 2022, holds a commanding position in California's 37th Congressional District primary held June 2, 2026. Partial results show her capturing over 54 percent of the vote in the heavily Democratic Los Angeles-area seat, well ahead of several Democratic challengers and the lone Republican candidate. Under the state's top-two primary system, the leading two finishers advance to the November general election irrespective of party. No major late developments have altered the trajectory, with the outcome likely to be confirmed once remaining mail ballots are tallied and certified.
