Our verdict

LiberalMind endorses Amanda McKinney

Election Day is Tuesday, November 3, 2026; Washington votes by mail, and ballots are in voters' hands. This is the whole race — the records, the claims against each candidate, and what the sources actually show. Read the research, and decide which flaw you can live with.

The setup

Washington's 4th District — central Washington, Yakima to the Tri-Cities — is an open seat. Rep. Dan Newhouse (R), first elected in 2014, is retiring and did not seek re-election, a fact verified across multiple independent sources. (One compilation dates his announcement "17 December 2026" — after Election Day, and plainly a source error; the retirement itself is not in doubt, and the bad date is not repeated as fact anywhere in this piece.) Eleven candidates ran in the August 4 primary. The finalists: Amanda McKinney (R), first with 34.8%, and John Duresky (D), the lone Democrat in the field, second with 29.9%. The district voted Trump 58.7% / Harris 38.1% in 2024 — Inside Elections calls it the most Republican district in the state — and the seat rates Solid R.

Amanda McKinney (Republican)

The record: McKinney is a Yakima County Commissioner of six years, a former mortgage banker whose family farms. She is endorsed by President Trump. Her work includes national county-association leadership on rural and wildfire issues. Her platform, per a Tri-City trade association's candidate guide (compilation strength): agriculture and water rights, dam protection, advanced nuclear and Hanford expansion, and border security.

Pros: The strongest nominee profile in Washington's long-tail set: a sitting elected county executive, a farming and banking biography rooted in the district's economy, the president's endorsement, and a plurality win in an eleven-candidate field.

Cons: County office is the ceiling of her record — she has not legislated at state or federal level, and a 34.8% primary plurality means most primary voters chose someone else, albeit from a field of eleven.

The flaw, plainly: McKinney's flaw is scale, not alignment: a proven county officeholder whose record has never been tested above the county line. That is a watch item under our criteria, not a demerit.

John Duresky (Democratic)

The record: Duresky, of West Richland, is a retired Air Force major with 24 years in cyberspace operations and a former project control officer and federal technology program manager at the Hanford nuclear site, where his programs exceeded $100 million a year. His platform, per the same trade-association guide: affordability, rural hospitals, ACA subsidies, farm bill and H-2A reform, and a congressional stock-trading ban.

Pros: A serious record — a military career and management of nine-figure federal programs at the district's largest employer. On biography alone, he is the most credentialed Democratic nominee in this state set.

Cons: His platform is his party's program — ACA subsidies defended, the farm bill as his party writes it — and his file contains no documented break with his party toward our values. Competence is not an exception; Manchin cases are built on breaks, and there are none here.

The flaw, plainly: Duresky's flaw is that his proof proves the wrong thing: an excellent résumé in service of the other party's caucus, in the most Republican district in the state.

OUR CALL

LiberalMind endorses Amanda McKinney.

This is the one open-seat race in Washington's set where the criteria have something to work with on both sides, and they are not close. McKinney is a sitting elected official, aligned on the district's defining questions — agriculture, water, the dams, Hanford, the border — and endorsed by the president. Duresky is a genuinely credentialed challenger whose platform is his party's program with no documented break. We endorse the commissioner, and we note for the record that the Democrat here was the strongest nominee his party fielded in this state — which is a comment on the rest of the slate, not a reason to give him a Republican seat.
