Recent national polling for Mexico’s June 2027 Chamber of Deputies election shows Morena maintaining a wide lead, leaving PAN positioned ahead of PRI, PVEM, MC, and PT among opposition parties. PAN’s edge stems from its stronger vote intention in multiple surveys, separate contestation after ending its prior alliance with PRI, and competitive standing in several state capitals and gubernatorial races. The fragmented opposition vote, with no unified front emerging, reinforces trader expectations that PAN will secure the second-highest seat total under proportional representation rules, while smaller allied or minor parties trail further behind. Upcoming candidate selections and alliance talks remain the main variables that could still shift relative positioning before election day.
