Amanda McKinney holds a commanding lead in Washington’s 4th Congressional District, an open seat after longtime Republican Dan Newhouse retired, because the district ranks among the state’s most conservative and delivered a 21-point margin for the Republican presidential candidate in 2024. McKinney, a Yakima County commissioner endorsed by President Trump, topped the August primary with 34.9% and has maintained a roughly 54-46% edge in early general-election returns as of November 4, supported by stronger fundraising and outside spending. Democrat John Duresky, a retired Air Force major, advanced from the primary but faces structural headwinds in a district where no Democrat has won since 1992. Trader consensus at 96.5% for McKinney reflects these fundamentals and the absence of major late developments. Only an unusually large shift in the remaining mail ballots or unforeseen events could realistically alter the outcome.
