Democrats sweep state legislatures, flipping Arizona and Pennsylvania in historic midterm wave

Democrats gained hundreds of state legislative seats in the 2026 midterms, securing full control of government in Arizona for the first time in 60 years and in Pennsylvania for the first time since the 1990s. The party is poised to pursue an aggressive legislative agenda at the state level, which could reshape policy on voting rights, abortion, and redistricting ahead of the 2030 census. Ballots are still being counted, so final seat tallies and the full scope of the wave remain uncertain.
