Michigan voters will decide on November 3, 2026, whether to convene a constitutional convention under the automatic 16-year review provision in the 1963 Constitution, with any resulting revisions subject to later voter approval. Trader consensus heavily favors rejection, consistent with prior outcomes in 1978, 1994, and 2010, where “no” votes exceeded 66 percent. Primary drivers include organized opposition from coalitions such as Protect MI Constitution, business groups, and the League of Women Voters, who cite risks of broad changes to recent amendments on redistricting, voting access, and reproductive policy. Limited endorsement from some Republican legislative leaders has not generated comparable mobilization. Historical patterns of voter preference for targeted citizen-initiated amendments over wholesale revision, combined with the multi-step process required for any new document, reinforce expectations of continuity through the November election.
