While La Jornada and Milenio covered the event quite differently, to put it mildly, of note is that in Cárdenas' public appearance at the anniversary of his mother's death, the old caudillo, while reiterating his opposition to PAN-PRD alliances, opened up for the possibility of such alliances as long as the candidate is from the PRD.
This, in stark opposition to his one-time protégé AMLO, who since 2009 on has rejected any such tactical alliance to defeat the PRI. Indeed, Cárdenas appeared even to open up for a 2012 presidential candidate of the PRD, backed by PAN. Of note here was the participation in the event of Manuel Camacho, the electoral alliance alchemist par excellance.
