Incumbent Democrat Adam Smith holds a commanding position in the Washington 9th congressional district race due to the seat’s entrenched Democratic lean, reflected in its D+22 partisan voting index and consistent Solid Democratic or Safe Democratic ratings from forecasters. Smith advanced comfortably from the August 2026 top-two primary to face Republican Doug Basler in the November general election, benefiting from his long tenure since 1997, substantial fundraising edge exceeding $1.8 million compared to Basler’s roughly $99,000, and the absence of viable primary threats. Traders assign over 96 percent probability to Smith, consistent with historical results and the district’s recent presidential margins, though a late national shift or major candidate development before Election Day could theoretically narrow the gap.
