The guerrilla leader of the Zapatista Army of National Liberation (EZLN), Subcomandante Marcos, said López Obrador was a false left-wing candidate, arguing that he was a centrist candidate. Cuauhtémoc Cárdenas did not participate in campaign events but stated that he would still vote for his party, the PRD.
