Recent national polling for Mexico’s June 2027 Chamber of Deputies election shows Morena maintaining a wide lead at 35-41 percent, leaving the fragmented opposition to contest second place. PAN registers the strongest consistent support among non-governing parties, typically 11-18 percent, ahead of PRI and MC, reflecting its established organizational base in key states and urban centers where it has outperformed rivals in recent local measurements. The decision by PAN to contest the election independently after ending its prior alliance with PRI, combined with MC’s separate strategy and PRI’s ongoing membership decline, has reinforced PAN’s position as the leading opposition contender without a unified front emerging to challenge that ranking. Traders’ heavy weighting toward PAN therefore tracks these stable survey patterns and the absence of major shifts in opposition dynamics over the past month.
