Will directly electing judges help Mexico fight corruption in its justice system?

Mexico’s outgoing President Andres Manuel Lopez Obrador has used his party's overwhelming democratic mandate to pass a series of reforms that will make the country the first in the world to elect almost all of its judges by popular vote. It’s a reform that the left-wing leader has championed as a crucial step to curtail the widespread corruption in Mexico’s judiciary – but some are worried it may leave the newly elected judges open to pressure from the country's powerful drug cartels, or even usher in a return to de facto one-party rule.
