Mexico Senate Presidency Race Heats Up Ahead of 2026‑27 Legislative Term

Senator Óscar Cantón Zetina of Morena announced his intention to run for the presidency of Mexico’s Senate for the 2026‑27 legislative period, describing the role as a high honor. He joins a field that includes fellow Morena senators Higinio Martínez, Manuel Huerta Ladrón de Guevara, and PVEM senator Jorge Carlos Ramírez Marín, as well as Gerardo Fernández Noroña, who is seeking a repeat despite a recent ruling that found him guilty of gender‑based political violence.

The current Senate president, Laura Itzel Castillo Juárez, will step down on 31 August 2026 to join President‑elect Claudia Sheinbaum’s cabinet as head of the Women’s Secretariat. Morena’s parliamentary coordinator Ignacio Mier has signaled that a more temperate and consensual candidate is needed, effectively ruling out Noroña’s re‑election. Speculation also surrounds a possible return of Marcelo Ebrard to the Senate to assume the presidency.

The internal debate within Morena reflects broader political tensions as the party prepares to guide the Senate’s agenda during a year expected to feature heightened confrontation in Mexican politics.
