Mexico’s president mounted a defiant display of national unity on Sunday, transforming a two-year electoral anniversary into a mass repudiation of what she termed United States interventionism. From the Monument to the Revolution, Claudia Sheinbaum addressed a sea of 130,000 supporters, while simultaneous gatherings in 31 state capitals amassed crowds totalling several hundred thousand more. ‘Mexico is nobody’s piñata,’ she declared, in a speech that blended social programme achievements with an escalating confrontation over drug-related indictments.

The immediate trigger for the bellicose tone was last month’s unsealing of US Department of Justice charges against Sinaloa’s governor and nine other officials for allegedly protecting the Chapitos faction of the Sinaloa cartel. Viewed from Washington, the case is a criminal matter; from the Mexican presidency, it represents a bid by ‘ultra-right’ forces to sway domestic politics, especially as mid-term elections approach in both nations. Sheinbaum pointed to the deaths of two CIA agents on Mexican soil in April as the start of an intensified campaign.

Across the republic, the choreography of loyalty was meticulously executed. Governors from Baja California to Yucatán led local rallies, with Sinaloa’s acting governor pledging support despite the indictment hanging over her predecessor. Seven Supreme Court justices attended the capital event, lending judicial imprimatur to the message. Analysts in London note this reflects a regime mobilising every lever to frame external pressure as an existential threat, thereby consolidating its own political base.

The president reserved especially harsh words for her predecessors, branding the Calderón administration a ‘narcogobierno’ and accusing him and others of hypocrisy. Former president Calderón, in turn, called for a non-partisan national security pact, but the rhetoric has effectively painted any internal criticism as collusion with foreign adversaries. Looking ahead, the strategy carries dual risks: it may stiffen Washington’s resolve, particularly if Republicans seek to use the issue in November elections, yet it also locks in the Morena movement’s narrative of patriotic resistance, making de‑escalation harder to achieve.
