Colombians are heading to the polls Sunday. With current president Gustavo Petro stepping down, the search for his successor is seen as a referendum on his leftist social policies and response to growing violence in the country. Left-wing candidate Ivan Cepeda, who says he will continue pursuing peace accords with armed groups, is leading in the polls. But he faces stark opposition from the more hawkish right. Trump-loving millionaire lawyer Abelardo de la Espriella and Paloma Valencia, who comes from one of Colombia’s most important conservative dynasties, both favor harsher crackdowns on guerrilla groups.
