Marni von Wilpert and Jim Desmond emerged as the front-runners in California’s 48th Congressional District primary and will face off in November for the seat represented by Darrell Issa. The race could affect Democratic hopes of retaking the House.
Von Wilpert, a Democrat, and Desmond, a Republican endorsed by President Donald Trump, led the field in the redrawn 48th District, which spans Riverside and San Diego Counties. The article says the district could be important to Democratic efforts to retake the House and has a Democratic voter-registration edge of about four percentage points.
Desmond serves on the San Diego County Board of Supervisors and previously was mayor of San Marcos. Von Wilpert has served on the San Diego City Council since 2020 and has worked as a civil prosecutor and in the Peace Corps. Issa announced his retirement in March, leaving the seat open.
