Washington's 10th congressional district has delivered Democratic victories in every election since its creation, supported by a D+9 Partisan Voter Index. Incumbent Marilyn Strickland advanced from the August 4, 2026 top-two primary with 49 percent, ahead of Republican Chris Chung at 33 percent, setting up a general election matchup on November 3. Forecasters including Cook Political Report, Sabato's Crystal Ball, and others rate the seat Solid or Safe Democratic, reflecting Strickland's incumbency, fundraising edge exceeding $1.5 million, and the district's consistent partisan lean. Trader consensus at 94.5 percent Democratic probability tracks these structural factors. A late national Republican wave, unforeseen scandal, or unusually suppressed Democratic turnout could narrow the margin, though no such developments have emerged in the current cycle.
