The sole argument from the right was their promise of violence towards the poors who turned to crime, that’s why they won according to most newspapers.
The homicide rate per 100,000 inhabitants fell from 18 in 2011 to 5.8 in 2017 under R.Correa(, president from 2007 to 2017), then rose up immediately afterwards, people seems to have a short memory apparently.

The solution for the right is to be more and more inhumane with criminals, while the solution from the left was to facilitate access to social programs for them, and reduce poverty.
