Incumbent Republican Michael Baumgartner holds an 80.5% implied probability in the WA-05 House race, reflecting the district’s Republican lean, his 2024 general election margin of over 20 points against the same Democratic opponent, and strong primary performance where he captured nearly half the vote in an all-party field. Carmela Conroy sits at 18.1% amid limited crossover appeal. Recent developments include the DCCC designating the contest a target in early October 2026, citing affordability concerns and Baumgartner’s primary share as signs of vulnerability, while both candidates have debated housing costs, trade policy, data centers, and foreign policy in forums through late September and early October. Nonpartisan ratings continue to classify the seat as solidly Republican ahead of the November 3 general election.
