Washington’s 4th congressional district maintains a Cook Partisan Voting Index of R+10 and has delivered consistent Republican margins in presidential and House contests, including Donald Trump’s double-digit victories in recent cycles. Incumbent Dan Newhouse’s retirement opened the seat, yet the August 4, 2026 top-two primary consolidated Republican support behind Yakima County Commissioner Amanda McKinney, who advanced alongside Democrat John Duresky. Voter registration patterns, county-level results across Yakima and the Tri-Cities, and the absence of competitive Democratic infrastructure sustain trader consensus reflected in the 90.5% Republican probability. A major national partisan shift, significant Republican nominee setbacks, or unusually high Democratic turnout could narrow the gap, though structural fundamentals make such reversals uncommon.

A candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time all of the 2026 House elections are conclusively called by this market's resolution sources. A candidate without a ballot-listed affiliation to either the Democrat or Republican parties will be considered a member of one of these parties based on the party with which they most recently expressed their intent to caucus at the time all of the House elections are conclusively called by this market's resolution sources.
This market will resolve based on the result of the election as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the United States government, specifically the Federal Election Commission (https://www.fec.gov/).
