Michigan voters will decide on November 3, 2026, whether to convene a constitutional convention under the automatic 16-year provision of the state constitution, with any approved convention scheduled for 2027. Historical precedent strongly favors rejection, as similar ballot questions failed by wide margins in 1978, 1994, and 2010. Organized opposition from groups focused on preserving existing provisions around taxes, redistricting, and term limits has mobilized early against the measure, citing risks of broad revisions and added taxpayer costs. With the election still months away and no major recent developments shifting public sentiment, trader consensus at 95.5% for “no” reflects this entrenched pattern. Late developments such as unexpected polling swings, high-profile endorsements, or economic pressures could still alter the trajectory before Election Day.
