In a follow-up to the San Luis Potosí 'Spouse Law' controversy, President Claudia Sheinbaum firmly rejected mandatory gender alternation for governorships on December 22, arguing the INE's parity quotas suffice. Morena continues to oppose the reform as unconstitutional.
Following Governor Ricardo Gallardo's defense of the 'Spouse Law'—which mandates a female nominee for the 2027 San Luis Potosí governorship—and amid Morena's unconstitutionality challenge, President Claudia Sheinbaum addressed the reform in her December 22, 2025, morning press conference.
Sheinbaum stated that such legislation is unnecessary, citing the National Electoral Institute (INE) requirement for parties to propose half female and half male candidates. 'I don't think this type of law is needed... parties have to propose half of their candidates women and the other half men,' she said.
For the 2027 elections with 17 governorships at stake, the INE ensures nine female and eight male slots. 'To avoid any sense that it's being directed or that someone is being prevented from participating, I don't think it's necessary to legislate man-woman alternation,' she added.
Morena President Luisa María Alcalde reiterated opposition, noting the party will apply its anti-nepotism reform early and pursue legal action. The law has drawn scrutiny for potentially favoring relatives like Senator Ruth González, wife of Governor Gallardo.
Sheinbaum urged state congresses to review the proposal but maintained INE parity promotes equality without coercive measures.
