Mexican opposition parties debate 2027 alliances and legal challenges

Mexican opposition parties are navigating internal divisions and strategic shifts ahead of the 2027 elections. The National Action Party (PAN) is facing internal friction regarding potential alliances with the Institutional Revolutionary Party (PRI). While some regional leaders in Sonora and Chihuahua express openness to coalitions, other militants in states like Yucatán and Nuevo León have criticized the national leadership for potentially compromising party principles.

In Puebla, the PAN has filed an unconstitutionality lawsuit with the Supreme Court of Justice of the Nation (SCJN) to challenge an electoral reform approved by the Morena-led legislature. The PAN argues that reducing the number of councilors (regidores) in the state's 217 municipalities undermines political plurality and democratic representation, particularly in Puebla Capital.

Meanwhile, PRI leader Alejandro ‘Alito’ Moreno is actively calling for a broad opposition coalition to challenge Morena's dominance. He suggests that while national-level dialogue may be stalled, state-level acercamientos are occurring. In Nayarit, Morena, the Green Party, and the Labor Party (PT) continue negotiations to maintain their alliance and define gubernatorial candidates for 2027.
