Political support for President Claudia Sheinbaum remains visible through large-scale marches and endorsements from groups like CNTE Section 22. However, the governing alliance is experiencing heightened tension regarding candidate selection for the 2027 gubernatorial elections.

The Labor Party (PT), led by federal deputy Reginaldo Sandoval Flores, has demanded that Morena repeat its internal surveys in 17 states using scientific and independent methodologies. The PT alleges that previous processes lacked transparency and were controlled by Morena, further accusing the ruling party of shifting its ideology toward the center-right.

Disputes have intensified in several regions. In Michoacán, the PT has backed Senator Raúl Morón Orozco and warned that if Morena does not conduct a new survey by November, the PT may nominate Morón as its own candidate. Similar demands for transparent polling have been raised in Colima, Zacatecas, and Nuevo León, where the PT is considering candidates such as Jesús Elizondo.

In response to these threats of rupture, Morena leader Ariadna Montiel Reyes has denied any imminent break with the PT or the Green Party (PVEM), stating that dialogue remains open and that the parties share common electoral and legislative goals. Meanwhile, in Querétaro, Santiago Nieto has called for unity, confirming the coalition with the PT and PVEM for the 2027 cycle.
