**Morena maintains a commanding position in Sonora ahead of the 2027 gubernatorial election, with party identification near 50% in recent polls and general-election support often exceeding 40-50%.** This structural edge makes the party's internal selection process the decisive factor for overall odds. Lorenia Valles Sampedro has led or placed at the top of multiple mid-2026 internal preference surveys, benefiting from stronger name recognition, favorable reputation balances, and head-to-head leads against likely opposition figures such as Antonio Astiazarán Gutiérrez or Luis Donaldo Colosio Riojas. Javier Lamarque Cano and Célida Teresa López Cárdenas remain competitive in the Morena field, while opposition and minor-party candidates trail significantly. The nomination, expected to conclude via party surveys in the coming weeks, will likely widen separation among contenders; late developments in the internal process or shifts in opposition consolidation could still adjust probabilities before the June 2027 vote.
