Who's In the Race

Washington's 4th U.S. House District pits Republican Amanda McKinney against Democrat John Duresky in an open-seat race. Rep. Dan Newhouse (R-WA) previously held the seat and is not running in 2026.

McKinney is the current Yakima County commissioner, raised in a family rooted in faith and agriculture, and describes herself as a wife and mother. Duresky is a retired Air Force major who spent 37 years in the Air Force and civil service. Newhouse won the district in 2024 with 52 percent of the vote and in 2022 with about 66 percent.

What They Stand For

McKinney describes her approach as common-sense conservative leadership. She says she supports secure borders, strong national defense, energy independence, free markets, and ending what she calls the weaponization of government. On energy, McKinney backs American production through hydropower, nuclear energy, natural gas, and domestic sources. Her stated congressional priorities include agriculture, water rights, law enforcement, and American values. McKinney says she opposed the Horse Heaven Hills wind project and objected to water-rights transfers and the project's effects on agricultural land and wildfire response.

Duresky says his priorities include supporting working families, farmers, and veterans, holding government accountable, and addressing rural healthcare. His campaign identifies agriculture, jobs, healthcare, veterans, and government accountability as central issue areas. Duresky argues that unchecked executive power and trade policies are damaging Central Washington agriculture and threatening Hanford-related jobs.

The Money Behind the Race

Outside groups have spent $2,258,821 in the race, all of it tied to Republican candidates. Disbursements indexed as supporting candidates came to $2,115,098, and those indexed as opposing them came to $143,723.

Outside spending totals in the records include American Mission ($779,341), Washington Rising Inc. ($700,727), Defend American Jobs ($506,917), Conservatives for American Excellence Inc. ($191,316), and WFW Action Fund Inc ($40,500). The committee totals reflect overall spending and do not indicate whether each committee supported or opposed a particular candidate.

Race Outlook: Ratings and Betting Markets

Cook Political Report rated the race Solid Republican as of Sept. 25, Sabato's Crystal Ball rated it Solid Republican as of Sept. 29, and Inside Elections rated it Solid Republican as of Oct. 2. On Kalshi, the prediction market gave McKinney a 92.78 percent chance of winning and Duresky a 7.22 percent chance, as of Oct. 5.

The district has elected a Republican in each of the last two cycles, with Newhouse winning about 66 percent in 2022 and about 52 percent in 2024. An index of races returned nine Democratic wins and two Republican wins, but the data does not confirm its year, office or completeness, so it is not a verified tally of Washington's congressional results for 2022 or 2024. In the 2024 presidential race, Democrat Kamala Harris carried Washington with 57.23 percent of the vote.

Voter registration, early voting, and Election Day polling hours for Washington's 4th District have not yet been published by the Washington Secretary of State, Elections Division as of Oct. 5. Washington's 4th Congressional District spans multiple counties, and any local variation in voting details would have to come from each county auditor's election office.
