Following the 2016 state senate elections, Republicans maintained effective control of the Senate, 25–24 because self-identified Democrat Tim Sheldon caucuses with the Republicans. However, in 2017 Democrats regained control of the Washington State Senate after Democrat Manka Dhingra won a special election in Washington's 45th legislative district.
Democrats expanded their caucus's majority to 28–21 by further flipping the 26th, 30th, and 47th districts. Tim Sheldon was reelected as a Democrat but continued to caucus with the Republicans.Overview
