Incumbent Democrat Marilyn Strickland advanced from Washington’s August 2026 top-two primary alongside Republican Chris Chung to contest the November 3 general election in the 10th congressional district. The district’s consistent Democratic lean, reflected in its D+9 Partisan Voter Index and historical election results, underpins trader pricing that heavily favors the Democratic nominee. Strickland’s multiple terms, substantial fundraising edge, and endorsements from labor groups further reinforce this positioning, while Chung’s profile remains limited following a primary where he finished well behind the incumbent. All major forecasters rate the seat Solid or Safe Democratic. A late-breaking scandal, health event affecting the incumbent, or unforeseen national political shift could theoretically narrow the margin, though such developments remain low-probability factors at this stage.
