With an approval rating of just 18% as he left office, Enrique Peña Nieto's presidency was marked by widespread public discontent and perceptions of corruption. His administration was plagued by scandals and controversies, including the disappearance of 43 students in Iguala, the Ayotzinapa case, and allegations of widespread graft. These factors contributed to a significant erosion of public trust and confidence in Peña Nieto's leadership.
