Internal friction within the Movimiento Ciudadano party in Sonora has led to a series of high-profile resignations. The instability began with Natalia Rivera Grijalva, the state coordinator, who resigned citing a lack of political congruence. Rivera Grijalva criticized the national leadership for incorporating a political group linked to former governor Guillermo Padrés Elías, a move she described as the arrival of “padrecismo” within the party.

Following this departure, several local officials also left the party. Four regidores—Adolfo Domínguez, Romeo Ernesto Porchas Serecer, Guillermo Ybarra Osuna, and Roberto Romero—resigned from their positions. While some officials joined the “Sonora Con Todo” movement to support Hermosillo Mayor Antonio Astiazarán, others cited personal and political reasons for their exit. Additionally, Jesús Francisco Elías Soto resigned, criticizing the party for bringing in politicians associated with previous state administrations.
