Former Mexico City mayor Claudia Sheinbaum to be the ruling party's presidential candidate

Claudia Sheinbaum, the former mayor of Mexico City, has been chosen as the ruling party's presidential candidate, making her the front-runner to become Mexico's first female president. Sheinbaum, a close ally of current President Lopez Obrador, won in five party surveys against her main rival, former Foreign Affairs Secretary Marcelo Ebrard. Sheinbaum's candidacy gives her a significant advantage in the June presidential election.
