Lorenia Valles Sampedro leads trader consensus at 64.5% following her late-September 2026 selection by Morena and PVEM as state coordinator for the defense of the transformation, after prevailing in the party's internal survey ahead of the June 2027 Sonora gubernatorial vote. This outcome reflects the ruling party's continuity strategy under outgoing Governor Alfonso Durazo, who backed her candidacy to maintain control of the state executive. Opposition figures trail, with Luis Donaldo Colosio Riojas at 19.7% as Movimiento Ciudadano's likely nominee and Antonio Astiazarán Gutiérrez at 7.8% for a potential PAN-PRI alliance. Recent polling in key municipalities shows Valles ahead, though the formal campaign period has not begun and coalition negotiations plus any PT split remain variables that could affect final ballot access.
