California's 27th congressional district holds its top-two primary on June 2, 2026, to select the two candidates advancing to the November general election. Incumbent Democratic Representative George Whitesides faces Democratic challengers Caleb Norwood and Roberto Ramos plus Republican Jason Gibbs in the nonpartisan contest. Recent redistricting under Proposition 50 removed conservative-leaning northern Los Angeles County areas, shifting the district to a stronger Democratic partisan lean according to nonpartisan ratings such as those from the Cook Political Report. With filing deadlines passed in March and no major late developments reported, the race centers on voter consolidation behind the incumbent and the limited field of Republican options in a district where Democratic registration and performance history favor one party securing both primary spots.
