Recent national polling for Mexico’s June 2027 Chamber of Deputies election shows Morena maintaining a clear lead in voting intention, while the opposition remains fragmented. Surveys from September and early October place PAN ahead of PRI and MC in second position, reflecting PAN’s stronger performance in traditional strongholds and higher standalone visibility. Traders assign PAN the highest probability for second place amid the absence of a broad opposition alliance and limited recent movement in party rankings. Upcoming precampaign periods and state-level contests could still shift relative standings before the June ballot.
