Michigan voters face an automatic ballot question in November 2026 on whether to convene a constitutional convention for a full rewrite of the 1963 state constitution, with the “No” side holding a narrow 54% trader consensus. Historical precedent favors rejection, as voters turned down similar proposals by wide margins in 1978, 1994, and 2010. Current balance stems from Republican legislative leaders endorsing the process to revisit recent voter-approved provisions on redistricting, reproductive rights, and term limits, offset by broad opposition from business, labor, education, and civic groups that warn of risks to established protections. Upcoming developments such as organized campaign spending, candidate positions in the 2026 elections, and any early polling could shift the implied probability in either direction before election day.
