Washington's 4th congressional district encompasses a large area ofcentral Washington, covering the counties ofDouglas,Okanogan,Grant,Yakima,Benton, andKlickitat; and parts ofAdams andFranklin counties. The district is dominated by theYakima andTri-Cities areas. With aCook Partisan Voting Index rating of R+10, it is the most Republican district in Washington.[2]
Its Republican dominance is long-established. Apart fromKlickitat 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 sinceBill Clinton in1992 carriedOkanogan County. None of the other counties in the district have backed a Democrat for President sinceLyndon B. Johnson in1964, whileAdams County has not voted Democratic sinceFranklin D. Roosevelt in1936.
John McCain won the district in2008 with 58% of the vote.Mitt Romney won the district with 60% in2012, whileDonald Trump won this district all three times he ran, with 57% in both2016 and2020, and 59% in2024. This district was the most Republican congressional district in the state in all five of those presidential elections.
Only threeDemocrats have ever represented the district in Congress. The last Democrat to represent the district wasJay Inslee, who held the seat during the103rd 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 toBainbridge Island and was sent back to Congress representing thefirst district in the centralPuget Sound area. Inslee was electedthe state's governor in 2012, and took office in January 2013. In the2008 election, Hastings easily defeated challenger George Fearing. The 4th district has been represented in theU.S. House of Representatives byDan Newhouse since2015, aRepublican fromSunnyside.
