Michigan voters face an automatic constitutional convention question on the November 2026 ballot, required every 16 years under the 1963 constitution, asking whether to elect delegates for a potential full revision in 2027. Trader consensus around a strong “no” outcome stems from repeated historical rejections, including a 67 percent defeat in 2010, combined with organized bipartisan opposition from labor unions, business chambers, conservation groups, and voting-rights organizations concerned about risks to existing provisions such as abortion rights and redistricting rules. Limited support from some Republican legislators has not generated broad momentum, and the preference for targeted citizen-initiated amendments over an open convention continues to shape assessments. Late developments such as unexpected polling shifts or major endorsements could still alter the trajectory before election day.
