PAN maintains a clear lead in trader pricing for second place in Mexico’s June 2027 Chamber of Deputies election, consistent with recent national polling that places the party ahead of or level with PRI and MC in a fragmented opposition field. Morena holds a wide advantage in voting intention, typically 35-41 percent, while the main opposition parties remain divided after PAN ended its prior national alliance with PRI and all three compete separately. Surveys from September and early October 2026 show PAN at 11-18 percent, PRI at 8-14 percent, and MC at 9-12 percent, with PVEM and PT registering lower single-digit support as smaller partners to the ruling bloc. Local alliance discussions and a sizable pool of undecided voters continue to shape positioning ahead of the June ballot.
