Morena maintains a structural lead in Sonora voter identification and intention-of-vote surveys ahead of the 2027 gubernatorial election, with the party and its allies consistently polling above 35-50 percent while opposition parties remain fragmented. Lorenia Valles Sampedro’s position at the top of recent internal Morena preference measurements and head-to-head scenarios stems from her registration as an aspirant in the party’s coordination process in June, combined with favorable reputation balances in multiple June-July polls. Competitive dynamics inside Morena, where Javier Lamarque Cano and Célida López remain close in some surveys, plus the possibility of opposition consolidation around figures such as Luis Donaldo Colosio or Antonio Astiazarán, keep probabilities compressed. Further movement will hinge on completion of the Morena internal selection and any shifts in opposition alliances before the election.
