Imelda Castro Castro holds the strongest position among contenders for the 2027 Sinaloa gubernatorial nomination within the dominant Morena party and its allies, while María Teresa Guerra Ochoa trails as another leading option. Recent internal party discussions emphasize selecting a female candidate for the state, amid the May 2026 resignation of incumbent Rubén Rocha over U.S. drug-related allegations and persistent cartel-linked security challenges. Trader consensus in the prediction market reflects these early nomination dynamics and Morena's structural advantage, with lower probabilities assigned to other listed aspirants. The race remains fluid until the official candidate selection and 2027 vote, where primary polling trends, coalition agreements, and any shifts in state security conditions could alter positioning.
