Imelda Castro Castro leads trader pricing for the 2027 Sinaloa governorship at 48.5 percent, ahead of María Teresa Guerra Ochoa at 16.5 percent, as the race centers on Morena’s internal coordination process for the nomination. Recent U.S. indictments and the abrupt second indefinite leave by incumbent Rubén Rocha Moya have intensified succession pressures inside the party, prompting alignment shifts among aspirants toward national leadership under President Sheinbaum. Early polling and registration data show Castro drawing support from her Senate record and broader party structures, while Guerra and other local figures retain backing from state networks. With the June 2027 election more than ten months away, formal candidate selection, coalition negotiations with allies such as the PT and PVEM, and ongoing security concerns remain key variables that could widen or narrow current implied probabilities.
