President Claudia Sheinbaum’s consolidation of control within Morena ahead of the June 2027 legislative elections has reinforced the party’s commanding position in voter surveys, where it consistently leads with support levels well above other parties. Recent internal party leadership transitions and strategic candidate selection efforts have strengthened coalition discipline among Morena allies, limiting opportunities for opposition gains by PAN, PRI, and Movimiento Ciudadano. Traders view these developments as sustaining the ruling party’s path to a majority in the Chamber of Deputies, with limited near-term catalysts capable of shifting the current distribution of implied probabilities.
