Redistricting shifted California's 48th District from a Republican stronghold to a lean-Democratic seat covering parts of San Diego and Riverside counties, prompting incumbent Darrell Issa to retire in March 2026. This opened a competitive top-two primary on June 2 where San Diego County Supervisor Jim Desmond, backed by Issa and President Trump, leads recent polling at 25-29 percent. A crowded Democratic field including Ammar Campa-Najjar, Marni von Wilpert, and Brandon Riker risks vote-splitting that could allow a second Republican to advance alongside Desmond. Ongoing Democratic infighting and endorsements from labor groups versus national Republicans shape the race dynamics ahead of the primary.
