Michigan Governor Race 2026 — Odds

MI · GovernorLean DOpen seat
Incumbent:Open seat

Gretchen Whitmer's term limit opens a three-way fight: Secretary of State Jocelyn Benson leads the Democratic field, Republicans coalesce around their nominee, and Detroit mayor Mike Duggan runs as an independent who could scramble both coalitions. Markets price Democrats in the mid-80s, notably more bullish than the Lean D consensus rating. The Duggan vote-split question makes this the most structurally uncertain big-state governor market.
