Hilda Solis holds a commanding lead in the California 38th congressional district general election due to the seat’s strong Democratic lean after recent redistricting, combined with her extensive prior service as a U.S. representative for overlapping areas, Obama-era labor secretary, and current Los Angeles County supervisor. She topped the June 2026 top-two primary with 47.6 percent against Republican Pedro Casas at 35.8 percent, advancing both candidates while eliminating other Democrats. Forecasters rate the race safe or solid Democratic, reflecting limited public polling and the district’s voter registration and past performance patterns. Casas, a first-time candidate and retired Army psychologist, faces structural barriers in a D+21 environment. Late national shifts in turnout, an unforeseen scandal, or health developments remain the primary factors that could still alter the implied probability ahead of the November 3 ballot.
