Incumbent Democratic Representative Ro Khanna dominated the June 2, 2026, nonpartisan top-two primary for California's 17th Congressional District, securing roughly 60 percent of the vote amid strong name recognition, fundraising advantages, and limited opposition from Democratic challengers Ethan Agarwal and Mike Katz. Republican candidates Ritesh Tandon and Jennie Ha Phan trailed, with early returns positioning Tandon for second place and advancement to the November general election under the state's top-two rules. Vote counting continues with mail and provisional ballots, though the outcome appears settled barring significant shifts. No major late-campaign events or endorsements altered the field in the weeks before the primary.
