(COMBO) This combination of file pictures created on May 31, 2024, shows Mexico's opposition presidential candidate, Xochitl Galvez (L), of the Fuerza y Corazon por Mexico coalition party, making a heart with her hands after signing the "Pact for Early Childhood" at the Papalote Museum in Mexico City on April 22, 2024, and Mexican leftist presidential candidate for the National Regeneration Movement (MORENA) party, Claudia Sheinbaum, making a heart with her hands during a campaign rally in Xochimilco, Mexico, on April 29, 2024. Millions of Mexicans are expected to vote for their first woman president in a landmark election on June 2, 2024, following a long and sometimes acrimonious race overshadowed by soaring political violence. Sheinbaum, a former Mexico City mayor and a scientist by training, was leading her main opposition rival Xochitl Galvez, also 61, by around 17 points in opinion polls days before the election. The only man running, 38-year-old centrist Jorge Alvarez Maynez, had just 11 percent. (Photo by Alfredo ESTRELLA and Yuri CORTEZ / AFP)
