Recent national polling for Mexico’s June 2027 Chamber of Deputies election shows Morena maintaining a wide lead in vote intention, leaving the contest for second place fragmented among opposition parties. PAN consistently registers the highest or near-highest support among non-Morena options in surveys from firms including LaEncuesta.mx, Mitofsky, and Buendía & Márquez, aided by its established organization, strength in several state capitals, and decision to contest districts independently rather than in a broad alliance. PRI and MC trail in most measures amid high rejection ratings and lower district-level competitiveness, while PVEM and PT remain smaller coalition partners with limited standalone reach. Traders price PAN highest for second place because its combination of national infrastructure and localized advantages positions it to secure more seats than fragmented rivals under Mexico’s mixed electoral system.
