Uruguay's politicians who led the charge to legalize marijuana and same-sex marriage appeared to win another ringing endorsement from voters in the South American country. Exit polls placed Tabaré Vazquez of the left-wing Broad Front coalition in the lead in the country's presidential runoff. Candidate Luis Lacalle Pou of the conservative National Party told supporters that he had conceded to Vazquez and wished him well. A win for Vazquez would give Uruguay a third consecutive five-year term with a leftist leader at the helm.
