Cuauhtémoc Cárdenas, a Mexican politician who never won the presidency, has died at 92, according to reports from The New York Times and ABC News. Both outlets reported his death, but the summaries available for this report describe his career in broad terms only.

The Times, in a report written by Anthony DePalma, described Cárdenas as the only son of a Mexican president. According to its summary, he never won the office but became a leading figure in the country's democratic transformation. Its headline identifies him as someone who helped end one-party rule in Mexico.

ABC News reported that Cárdenas, a former Mexican presidential candidate, has died at 92. Its summary does not mention his father, his family background, or his role in the country's democratic transformation.

The two reports differ in emphasis. The Times framed Cárdenas through his family and his part in political change, while ABC News framed him through his candidacy. As summarized, neither the Times nor ABC News gives a cause of death, a place of death, or the circumstances surrounding it.

The summaries available for this report do not include further details about Cárdenas's career, the history of one-party rule in Mexico, or reactions to his death. This report does not add information beyond what the two summaries contain.
