Morena holds a commanding lead in trader consensus for the June 2027 Mexican Chamber of Deputies election, driven by consistent national polling advantages of 20–30 points over fragmented opposition parties. Recent surveys, including Buendía & Márquez and La Encuesta MX from mid-to-late 2026, show Morena at 35–45% voting intention, supported by its position as the incumbent ruling party under President Claudia Sheinbaum and established alliances with PT and PVEM. Opposition parties such as PAN, PRI, and MC trail individually in the low-to-mid teens, with limited evidence of unified coalitions materializing in time to close the gap. These patterns reflect Morena’s organizational strength and broad geographic base heading into the contest for all 500 seats.
