Mexico had a complicated year in 2015. It was a critical mid-term election year, organized under new electoral rules, amidst social unrest, insecurity and political violence accompanied by an increasing social disaffection with politics. After three years in office, President Peña Nieto faced adverse economic conditions and a significant decrease in approval rates after damaging events such as the Ayotzinapa tragedy, corruption scandals and low economic
growth. However, due to an unprecedented vote fragmentation, the ruling coalition was able to retain its majority in the Chamber of Deputies.
