Mexicans will head to the polls to elect a new president on Sunday.

Meet Andrés Manuel López Obrador, the front-runner since the beginning of the year, who could bring about the most drastic change Mexico has seen in recent years.

Don’t miss: What investors need to know about Mexico’s presidential election[1]

Who is AMLO?

López Obrador, widely known by his initials as AMLO, is running for the leftist Morena party, which he founded himself in 2014. Morena is a Spanish acronym for the National Regeneration Movement, or Movimiento Regeneración Nacional. López Obrador is the former mayor of Mexico City and has run for president twice before, though on labor platforms and not under Morena’s banner.

The 64-year-old’s key campaign promises included counteracting corruption, decentralizing the federal government and provide access to free education on all levels. Energy sector proposals are also high on the candidate’s priority list. On the campaign trail, he said he would stop awarding oil contracts to private companies and halt the privatization of the electricity sector, a sharp break from the...
