Amanda McKinney holds a commanding lead in the WA-04 House race due to the district’s strong Republican tilt, confirmed by Cook Political Report, Sabato’s Crystal Ball, and other forecasters rating it Solid Republican. As an open seat following Dan Newhouse’s retirement, McKinney consolidated GOP support by winning the August 2026 top-two primary with 35% against a fragmented Republican field, advancing ahead of Democrat John Duresky at 30%. Her advantages include Trump and House Speaker endorsements, nearly $1 million in fundraising compared to Duresky’s $179,000, and outside spending from aligned super PACs. Recent candidate debates have highlighted divides on immigration enforcement and election security. Scenarios that could narrow the gap include major late-cycle scandals, health developments, or unusually high Democratic turnout in this conservative central Washington district.
