In Mexico, two mayoral candidates from the state of Michoacán were killed Monday, within hours of each other. Miguel Ángel Zavala and Armando Pérez Luna were preparing to begin their campaigns for mayor of Maravatío in the coming days when they were gunned down in separate incidents. Both candidates were found shot to death in their cars. Many have warned Mexico’s upcoming June election could be one of the most violent on record. Michoacán has been at the center of drug cartel fighting over territorial control. Zavala was a gynecologist, running with President Andrés Manuel López Obrador’s party Morena; Luna was the mayoral candidate for the conservative National Action Party.
