Recent polling from October 2026 shows the PVEM leading party preferences in San Luis Potosí by 16–20 points over Morena ahead of the 2027 state elections, which include renewal of the 27-seat Congress. This positioning aligns with the PVEM's current legislative role, including its deputy holding the congress presidency, and recent approval of electoral reforms setting rules for the July 2027 vote. Morena's decision to contest separately without a PVEM alliance has fragmented the former coalition, while opposition parties such as PAN, MC, PT, and PRI register lower single-digit or low-teen support in available surveys. Traders' consensus on the PVEM reflects these sustained polling gaps and institutional standing, with lower probabilities assigned to fragmented challengers.
