Michigan voters face an automatic ballot question on November 3, 2026, asking whether to convene a constitutional convention for a general revision of the 1963 state constitution. Trader consensus heavily favors rejection at 96 percent implied probability, driven by the measure’s consistent historical defeats—including a 66.6 percent no vote in 2010—and the emergence of a broad bipartisan opposition coalition backed by labor unions, business groups, and former officials from both parties. Recent polls show a narrow plurality for yes but substantial undecided voters, while organized “no” campaigns emphasize risks of interest-group influence and contrast the process with targeted amendment routes. Late shifts in turnout, endorsements, or campaign intensity remain the primary variables that could still alter the outcome before election day.
