Incumbent Rep. Dan Newhouse's December 2025 retirement opened Washington's 4th Congressional District, a solidly Republican seat with R+10 Cook PVI where Donald Trump won 59% in 2024, anchoring trader consensus at 80.5% for a GOP victory. The May 8 filing deadline revealed a crowded Republican primary field featuring well-funded Amanda McKinney ($451,000 cash on hand as of March) and state Sen. Matt Boehnke, backed by a former congressman, against Democrat John Duresky as the lone major-party challenger ($42,000 cash). Absent polls, the top-two primary on August 4 likely advances two Republicans to the November general, reinforcing historical GOP dominance despite the open race.
