Mexico’s ruling coalition—comprising the National Regeneration Movement (Morena), the Labour Party (PT), and the Green Party (PVEM)—formally reaffirmed its alliance in January 2026, setting the stage for a coordinated campaign in the 2027 midterm elections. The joint declaration, signed in Mexico City by party leaders, emphasized unity around President Claudia Sheinbaum’s national project and a shared commitment to maintaining legislative dominance.
The 2027 vote will renew all 500 seats in the Chamber of Deputies and is widely seen as a referendum on Sheinbaum’s first three years in office. The early reaffirmation of the alliance appears designed to consolidate candidate selection processes and deter internal fragmentation as electoral preparations begin.
Alberto Anaya, PT’s long-standing leader, framed the coalition as an enduring ideological alignment. He pledged that PT would remain allied with Morena through at least 2030, describing the party as a ‘natural and eternal ally of the left’ in Mexico. This continuity builds on previous joint campaigns in 2018, 2021, and 2024, during which the coalition secured congressional majorities.

Despite this show of unity, signs of divergence have emerged. PT legislators declined to endorse any potential electoral reform proposals currently under discussion within Morena or by the Presidential Commission for Electoral Reform. Citing the absence of a formal draft in Congress, PT lawmaker Benjamín Robles stated that his party would not comment on hypothetical reforms and would oppose any measures perceived as democratic setbacks.
This cautious stance suggests that while the coalition remains intact at the leadership level, legislative priorities may not be fully aligned. Electoral reform has been a contentious issue in recent years, and internal disagreements could test the resilience of the alliance as policy debates intensify ahead of 2027.
Still, by reaffirming their partnership early in the electoral cycle, Morena, PT, and PVEM signal a strategic intent to present a unified front. The move may also serve to reassure supporters and potential candidates that internal cohesion remains a priority despite underlying tensions.
