Marea Rosa: Largest Anti-AMLO Protest of His Presidency

The largest anti-AMLO protest of his presidency took place on February 26, 2023, as tens of thousands wearing pink and white overflowed Mexico City's Zócalo (capacity ~100,000), with crowds spilling onto adjoining streets. The march — nicknamed 'Marea Rosa' (Pink Tide) — opposed Plan B electoral reform. The movement included opposition parties (PAN, PRI, PRD, MC) plus nonpartisan civil society groups. AMLO the following morning acknowledged the marchers' right to protest. The mobilization was widely seen as a test run for broader opposition coordination ahead of the 2024 presidential election.
