Michigan voters will decide on November 3, 2026, whether to convene a constitutional convention under the automatic 16-year referendum required by the state constitution. Trader consensus for rejection aligns with prior outcomes, where similar questions were defeated by wide margins in 1978, 1994, and 2010. Recent developments include organized opposition from coalitions of business, labor, and good-government groups citing risks of broad structural changes to taxation, redistricting, term limits, and local authority. With the election still months away, the absence of strong organized support or polling shifts favoring approval reinforces expectations that voters will retain the 1963 framework. Unforeseen late developments such as major endorsements or turnout anomalies remain the primary variables that could alter the trajectory.
