|percent more than one race = 3.8 Washington's 4th congressional district encompasses a large area of central Washington, covering the counties of Douglas, Okanogan, Grant, Yakima, Benton, and Klickitat; and parts of Adams and Franklin counties. The district is dominated by the Yakima and Tri-Cities areas. With a Cook Partisan Voting Index rating of R+10, it is the most Republican district in Washington.
Its Republican dominance is long-established. Apart from Klickitat County, which was won six times by Democrats between 1968 and 2008 — though never with more than 51 percent of the ballots — no Democratic presidential candidate has carried any county in the district since Bill Clinton in 1992 carried Okanogan County. None of the other counties in the district have backed a Democrat for President since Lyndon B. Johnson in 1964, while Adams County has not voted Democratic since Franklin D. Roosevelt in 1936.
John McCain won the district in 2008 with 58% of the vote. Mitt Romney won the district with 60% in 2012, while Donald Trump won this district all three times he ran, with 57% in both 2016 and 2020, and 59% in 2024. This district was the most Republican congressional district in the state in all five of those presidential elections.
Only three Democrats have ever represented the district in Congress. The last Democrat to represent the district was Jay Inslee, who held the seat during the 103rd Congress. Doc Hastings, Inslee's Republican opponent in 1992, defeated Inslee in a 1994 rematch and served in Congress until he retired in 2014. After losing to Hastings in 1994, Inslee later moved to Bainbridge Island and was sent back to Congress representing the first district in the central Puget Sound area. Inslee was elected the state's governor in 2012, and took office in January 2013. In the 2008 election, Hastings easily defeated challenger George Fearing. The 4th district has been represented in the U.S. House of Representatives by Dan Newhouse since 2015, a Republican from Sunnyside.
