Michigan voters face an automatic ballot question on November 3, 2026, asking whether to convene a constitutional convention in 2027 to draft a full revision of the 1963 state constitution. Historical precedent strongly favors rejection, with voters turning down similar proposals by margins of 67 percent in 2010, 72 percent in 1994, and 77 percent in 1978. Recent developments have reinforced this pattern, as the Michigan Education Association, League of Women Voters of Michigan, and a newly formed bipartisan coalition have publicly endorsed a no vote, citing risks of unpredictable delegate outcomes and potential changes to education funding, labor provisions, and recently enacted ballot measures. Limited organized support for approval from legislative leaders and the absence of a robust yes campaign have kept the implied probability of rejection near 56.5 percent in trader assessments.
