Incumbent Democratic Rep. Marie Gluesenkamp Perez holds a strong position in Washington’s 3rd Congressional District heading into the November 3 general election. She advanced from the August top-two primary alongside Republican state Sen. John Braun after Democratic candidates collectively captured over 55% of the vote, exceeding recent Republican totals in a district Trump carried in 2024. Perez benefits from incumbency, a substantial fundraising edge exceeding $6 million to Braun’s roughly $2 million, and a centrist record that has sustained support in this swing seat. Braun, endorsed by Trump and backed by outside groups including a Trump-aligned PAC, remains competitive in a race rated toss-up or lean Democratic by most forecasters, though primary vote consolidation and historical margins favor the incumbent’s reelection odds in trader assessments.
