Michigan voters will decide Proposal 1 on November 3, 2026, an automatic ballot question required every 16 years under the state constitution that asks whether to convene a convention of elected delegates to consider a general revision. Historical precedent strongly favors rejection, with prior votes in 1978, 1994, and 2010 failing by margins of roughly two-to-one amid low information and concerns over unpredictable outcomes. Bipartisan opposition has formed through groups highlighting risks of special-interest influence and major structural changes, while organized support remains limited. Recent polls show Yes support near 47 percent with substantial undecided voters, yet trader consensus reflects the durable pattern of voters defaulting to the status quo on wholesale constitutional revision rather than incremental amendments. Late shifts in turnout, campaign intensity, or polling trends represent the primary variables that could alter the result before election day.
