Democrats Claim Supermajority in Washington State House

The Washington State Democratic Party claimed a supermajority victory in the state House of Representatives on November 7, 2026. Current tallies indicate Democrats will hold 66 of the 98 available seats, a level of control not seen by the party since 1949. This threshold allows the party to suspend legislative rules and increases their negotiating power; if the Senate also achieves a supermajority, Democrats could override gubernatorial vetoes and pass constitutional amendments.

Democratic gains were concentrated in the 14th, 17th, 18th, and 26th legislative districts. In the 14th District, candidates Chelsea Dimas and Ezequiel Morfin led their respective races. Several Republican incumbents conceded or acknowledged they were unlikely to overcome their deficits, including Kevin Waters, David Stuebe, and John Ley.

The Washington State Republican Party described the supermajority claim as premature while ballots continue to be counted. However, Republican Chair Jim Walsh admitted that numbers look poor for incumbents in the 17th and 18th districts. House Majority Leader Joe Fitzgibbon noted that the expanded caucus would bring more diversity and varied life experiences to the legislature.
