The Race

Democrat Doris Matsui is defending her seat in California's 7th U.S. House District, facing a crowded field in both the primary and general elections. The primary was held on June 2, 2026, with five candidates competing for the nomination. Matsui narrowly won with 29.1% of the vote, edged out by progressive challenger Mai Vang, who captured 30.8%. Now, with six candidates on the November 3, 2026 general election ballot, the race is heating up in a district long considered safely Democratic.
