Maryland voters face Question 3 on November 3, 2026, a legislatively referred constitutional amendment that would limit existing contiguity and compactness rules to state legislative districts while clarifying that the state constitution imposes no criteria on congressional boundaries and authorizing Supreme Court original jurisdiction over challenges. A recent UMBC poll shows 53% opposition among likely voters, aligning with current trader consensus, driven by partisan splits where most Republicans and independents oppose the measure while Democratic support remains divided. The amendment, advanced by the Democratic-controlled General Assembly during an August special session and upheld by the state Supreme Court in September after lower court blocks, sits in a competitive position due to high undecided shares, ongoing ad campaigns framing the issue around national redistricting fights, and voter concerns over potential mid-decade map changes that could affect the state's sole Republican-held House seat. Turnout patterns, further polling shifts, or clearer messaging on implications for future districting could alter the balance before election day.
