PAN maintains a consistent lead in national polling averages for the 2027 Chamber of Deputies election, placing it well ahead of other opposition parties and positioning it as the strongest candidate for second place behind Morena. Recent surveys from LaEncuesta.mx, Buendía & Márquez, and Mitofsky show PAN support in the 11-18% range, exceeding PRI and MC figures amid a fragmented opposition. The PAN's decision to contest the election independently after ending its prior alliance with the PRI has reinforced its standalone standing, while PRI and MC trail with more limited national reach. Morena's sustained lead above 35% narrows focus on which opposition party secures the next-highest vote share, with trader consensus reflecting these stable polling patterns and limited recent shifts in party positioning.
