Maryland voters will decide Question 3 on November 3, 2026, a legislatively referred constitutional amendment that would limit existing compactness and boundary requirements to state legislative districts only, remove state constitutional criteria for congressional districts, and authorize the Maryland Supreme Court to hear related challenges directly. The Democratic-controlled General Assembly approved the measure during an August 2026 special session, and Governor Wes Moore signed it. Lower courts initially blocked it from the ballot on procedural and single-subject grounds, but the state Supreme Court on September 3 reversed those rulings in part, ordering revised ballot language while confirming the question’s placement. In a state where Democrats hold seven of eight U.S. House seats, traders appear to view passage as more likely than not, though the outcome remains subject to turnout, campaign messaging on redistricting standards, and any late developments before election day.
