In 2023, six politicians of Morena toured Mexico, among them Claudia Sheinbaum, Marcelo Ebrard and Adán Augusto López. They were competing to lead “la Coordinación Nacional de los Comités de Defensa de la Cuarta Transformación 2024-2030” (the national coordination of the committees for the defense of the Fourth Transformation 2024-2030). The press called them corcholatas, bottle caps.
The complaints commission of the electoral institute INE set rules for the tours. The aspirants could not call for votes for or against any person or political force. Their activities could not seek support for a nomination as precandidates, and their propaganda had to identify the internal selection process. On July 11, 2023, the Superior Chamber of the electoral tribunal confirmed these rules by a majority of four votes. (Video in Spanish.)
