Michigan voters face an automatic constitutional convention question on the November 2026 ballot, required every 16 years under the state constitution. Historical patterns drive the strong trader consensus against approval, as voters rejected similar proposals by wide margins in 2010 and prior cycles. Opposition coalitions, including groups focused on preserving recent amendments on redistricting, voting access, and reproductive rights, have mobilized against broad revision. Proponents, including some legislative leaders, argue for updates to address structural issues, yet no recent polling or campaign developments indicate a shift from past outcomes. A yes vote would trigger delegate elections and a subsequent ratification ballot, but established voter behavior and limited momentum sustain expectations that the measure will fail. Late-breaking events, such as major scandals or coordinated campaigns, remain the primary variables that could alter probabilities before election day.
