Virginia voters narrowly approved a redistricting referendum on April 21, 2026 that redraws congressional districts in ways favorable to Democrats, potentially opening the door for the party to gain as many as four additional House seats in the midterms. The referendum passed with roughly a 2-3 point margin despite heavy spending and advertising from both sides. Republicans had opposed the measure as partisan gerrymandering, while Democrats argued the previous map did not fairly reflect the state's voting patterns.
