Cuauhtémoc Cárdenas, Mexican left leader who challenged the PRI, dies at 92

A life in the opposition

Cuauhtémoc Cárdenas died on Wednesday, 28 October 2026, at the age of 92, and President Claudia Sheinbaum announced the death on X. The cause of death was not immediately clear. He was the son of General Lázaro Cárdenas, who governed Mexico from 1934 to 1940 and is remembered for nationalising the oil industry. Cárdenas ran three times for the presidency without winning it, yet he is credited with helping to break the ruling party's long grip on national power.

The 1988 election and the PRD

His breakthrough came in 1988, when he ran for president against the PRI, the party that dominated the country at the time. The opposition alleged fraud and irregularities in the count, and Cárdenas was officially declared the loser. The dispute became a turning point for the opposition movement and for his later career. After leaving the PRI, he helped found the Party of the Democratic Revolution (PRD) in 1989, which grew into a leading force on the Mexican left. He stood again in 1994 and 2000 without winning. In 1997 he became the first elected head of government of Mexico City. In 2014 he resigned from the PRD, criticising the party leadership for its prolonged silence and for deep differences over how to address internal problems.

Tributes from across the political spectrum

Sheinbaum, who had herself been active in the PRD before the creation of Morena, praised him in her message on X.

“A man of firm principles who transformed our country's political life.”

Former president Andrés Manuel López Obrador, who co-founded the PRD with Cárdenas, also paid tribute to him.

“Without him, the country's political reality would be different.”

Ricardo Monreal, who leads Morena's parliamentary group, wrote in his own tribute that Cárdenas was an exemplary figure.

“He was a man of integrity, a democrat of firm convictions and an undisputed reference point for the Mexican left.”

Jorge Romero, leader of the conservative PAN, acknowledged his contribution to Mexican democracy, and PRI leader Alejandro Moreno recognised his important mark on the country. The PRI's parliamentary group also mourned him, although Cárdenas had spent 25 years in the party before breaking away. In 2014, when Sheinbaum published her university thesis, she added the phrase "year in which Cárdenas won" beneath the date.
