Morena holds a commanding lead in recent national polling for Mexico’s 2027 Chamber of Deputies election, registering 35–45% voting intention across multiple surveys conducted through late September 2026, well ahead of the PAN, PRI, and Movimiento Ciudadano. This reflects the party’s continued dominance as the governing force under President Claudia Sheinbaum, bolstered by its organizational reach and voter base. The opposition remains fragmented, with no single challenger exceeding roughly 18% support, limiting any path to a plurality. Recent internal Morena processes for candidate selection and alliance approvals with the PVEM and PT have reinforced expectations of coordinated strength, while uncertainty persists over whether the ruling bloc will retain a legislative majority. Trader consensus aligns closely with these polling patterns and structural advantages.
