Michigan voters face Proposal 1 on the November 3, 2026 ballot, an automatic question every 16 years asking whether to convene a constitutional convention for a general revision of the state constitution. Recent polling indicates opposition, with one October survey showing 51% against and 26% in favor among likely voters, while earlier September results had yes at 47% and no at 31% with substantial undecideds. A broad coalition spanning chambers of commerce, labor unions, the ACLU, Catholic Conference, and both abortion-rights and anti-abortion groups has organized under “Protect MI Constitution From Special Interests,” citing risks to recently enacted provisions such as reproductive rights and uncertainty over delegate selection and outcomes. Historical precedent reinforces the current trader consensus, as voters rejected similar calls in 1978, 1994, and 2010 by wide margins.
