Incumbent Democrat Marie Gluesenkamp Perez seeks a third term in Washington's competitive 3rd Congressional District under the state's top-two primary system, where the August 4, 2026, vote advances the top two finishers to November regardless of party. State Senate Minority Leader John Braun emerges as her principal Republican challenger, positioning the race as a key battleground after Perez's narrow prior victories in this Trump-won district. Her frequent cross-party votes, highlighted in January statements aligning with southwest Washington priorities, bolster her centrist appeal amid GOP efforts to reclaim the seat. No major developments in the past 30 days; traders monitor fundraising, endorsements, and early polling ahead of the primary.
