Incumbent Representative Ro Khanna enters the June 2, 2026, top-two primary for California's 17th congressional district with substantial advantages in fundraising and name recognition against Democratic challengers Ethan Agarwal and Mike Katz plus Republican candidates Ritesh Tandon and Jennie Ha Phan. The district's strong Democratic voter registration and unchanged boundaries after recent redistricting reinforce expectations that the two highest vote-getters will advance to November regardless of party. Agarwal's challenge, launched earlier this year and centered on policy critiques, has drawn some attention but shows limited momentum so far. No major campaign events or endorsements have shifted the field in recent weeks, leaving the primary outcome likely to hinge on turnout among established Democratic voters in Santa Clara and Alameda counties.
