The open seat in California's 48th congressional district, following Republican incumbent Darrell Issa's retirement, has become a targeted contest after redistricting under Proposition 50 shifted its partisan lean toward Democrats, with registration now showing 37% Democratic, 33% Republican, and 22% no party preference voters. Democrat Marni von Wilpert, a San Diego city councilmember, and Republican Jim Desmond, a county supervisor, advanced from the June 2026 top-two primary to face off in the November 3 general election. An early July poll placed von Wilpert narrowly ahead at 48% to 46%, within the margin of error, while forecasting models rate the race as leaning Democratic based on voter fundamentals and recent trends. Trader consensus on the Democratic outcome reflects these structural and polling signals in a district previously held by Republicans.
