Incumbent Democrat Kim Schrier secured over 53 percent in Washington’s August 4, 2026, top-two primary, advancing comfortably against a fragmented Republican field that split its support among multiple candidates. The district’s D+3 Partisan Voter Index, combined with consistent Solid or Likely Democratic ratings from major forecasters, underpins trader consensus for a Democratic hold. Schrier’s established incumbency since 2018, substantial fundraising edge, and the suburban eastern Seattle profile of the seat have reinforced this positioning ahead of the November 3 general election against Republican Spencer Meline. A national partisan shift, unusually low turnout, or significant late-cycle developments would be required to alter the outcome.
