Michigan voters face an automatic ballot question on November 3, 2026, asking whether to convene a constitutional convention for a general revision of the 1963 state constitution. Historical precedent strongly favors rejection, as voters turned down the measure by wide margins in 1978, 1994, and 2010. A broad coalition spanning business groups, labor unions, the ACLU, religious organizations, and both sides of the abortion debate has mobilized against Proposal 1, citing risks of unpredictable changes to provisions on rights, taxes, term limits, and initiative processes. Recent polling shows a plurality in support but substantial undecided voters, consistent with past patterns where opposition consolidated ahead of the election.
