Incumbent Democratic Representative Marie Gluesenkamp Perez holds a strong position in Washington’s 3rd Congressional District ahead of the November 2026 general election. The district’s Cook Partisan Voter Index of R+2 and her narrow 2024 victory with 51.7 percent of the vote create a competitive environment where her moderate voting record and incumbency provide measurable advantages. Recent candidate filing in early May 2026 has clarified the field for the August 4 top-two primary, with potential Republican challengers including state Senate Minority Leader John Braun. Forecasters rate the race as a toss-up or lean Democratic, and trader pricing reflects the historical resilience of sitting members in similar battleground seats despite polling volatility from earlier surveys.
