Washington’s 3rd Congressional District holds its nonpartisan top-two primary on August 4, 2026, with the two highest vote-getters advancing to the November general election. Incumbent Democrat Marie Gluesenkamp Pérez faces a primary challenge from Brent Hennrich, who has positioned himself as a more progressive alternative. On the Republican side, state Senate Minority Leader John Braun has emerged as the leading contender after filing closed in May, drawing national party support and endorsements. Additional candidates, including Austin Braswell and several Republicans, have entered the field but trail in early visibility and fundraising. The district’s competitive profile and recent candidate filings shape trader focus on which two names will appear on the general ballot.
