Mexicans lined up to vote for a new president on Sunday.
Opinion polls before the election showed a double-digit lead for Andres Manuel Lopez Obrador.
Obrador is a former Mexico City mayor expected to sharpen divisions with U.S. President Trump if he wins.
Lopez Obrador, 64, would be the first leftist president in decades in Mexico.
Since the race began late last year, at least 133 politicians have been murdered from all the major parties.
