For the first time in more than a decade, voters across Central Washington cast ballots on Tuesday without Congressman Dan Newhouse’s name among the choices, closing out a race in which eleven candidates have spent months jostling to succeed him in one of the country’s most reliably conservative House districts.
Newhouse, a farmer from Sunnyside who has represented Washington’s 4th Congressional District since 2015, announced in December that he would not seek a seventh term, ending a run during which he championed hydropower interests, agricultural labour reform and restrictions on Chinese purchases of American farmland. His departure has thrown open a district that stretches from the Oregon border to Canada, taking in the Tri-Cities, Yakima, Moses Lake and Omak, and which no Democratic challenger has carried past 37.2 per cent of the vote in a general election since Newhouse first won the seat.

The field that emerged to contest the seat splintered heavily along Republican lines, with six Republicans, one Democrat and several independents and minor-party contenders on the ballot, according to US-based networks. Yakima County Commissioner Amanda McKinney led early fundraising with more than $215,000 raised, while Jerrod Sessler, a Navy veteran who previously challenged Newhouse directly in 2024, entered the race again after leaning heavily on his earlier endorsement from Trump. Matt Boehnke also featured among the field’s stronger fundraisers, according to regional broadcasters.
One notable outlier was Republican candidate Vaz, a Seattle-based technology professional who chose to run in the district despite living outside it, telling the Yakima Herald that his decision reflected where he believed the state’s most consequential political issues were concentrated rather than any formal residency requirement, since the US Constitution only obliges House members to live within the state they represent.

Analysts have pointed to the splintering of the Republican vote as the central dynamic shaping Tuesday’s result. Todd Schaefer, chair of the political science department at Central Washington University, told the Spokesman-Review that with several Republicans dividing the conservative vote, the race would likely function much like a traditional partisan primary in practice, since Democrats were not expected to gather enough support to break through.
Unlike in 2024, when moderate and left-leaning voters helped Newhouse defeat a fellow Republican who had finished ahead of him in the primary, Democrats in the district appeared to have consolidated behind a single candidate this cycle rather than splitting their limited influence further.

Beyond the immediate contest, observers say the race carries significance for the direction of the national Republican Party as Trump’s influence continues to shape primary contests nationwide. One recent report framed the district as a potential bellwether for Republican politics amid rising voter frustration over affordability, artificial intelligence data centres and tariffs, themes that have surfaced repeatedly on the campaign trail this cycle.
Under Washington’s top-two primary system, all eleven candidates appeared together on Tuesday’s ballot regardless of party, with only the top two vote-getters advancing to the November general election. Ballots had already been mailed to registered voters ahead of Tuesday, consistent with the state’s vote-by-mail system in place since 2011, and county canvassing boards are due to certify results by 18th August, ahead of the secretary of state’s final certification deadline of 21st August. Results from Tuesday’s vote were still being tabulated as of Tuesday evening, with the closely divided Republican field expected to make the final order of finish unusually difficult to call.
