Morena maintains a substantial lead in Sonora voter intention surveys ahead of the June 2027 gubernatorial election, with party identification near 45-50 percent in multiple 2026 measurements. This underpins trader pricing that places Lorenia Valles Sampedro at the head of the field, reflecting her position as the frontrunner in Morena internal polling, her alignment with outgoing Governor Alfonso Durazo, and her recent Senate license to pursue the state coordination role. Javier Lamarque Cano remains a close internal rival, while opposition contenders such as Luis Donaldo Colosio Riojas and Antonio Astiazarán Gutiérrez register lower support in head-to-head scenarios. The narrow gaps among leading probabilities mirror ongoing uncertainty over the Morena nominee and limited recent shifts in statewide polling aggregates. Upcoming internal party processes and candidate registration deadlines could alter positioning before the general campaign intensifies.
