(CNN) -- Less than six weeks after President Hugo Chavez's death, Venezuelans will head to the polls Sunday to pick a new leader. It will be the second time in just over six months that voters in the south American country have cast ballots in a presidential election. Chavez, who ruled Venezuela for 14 years, celebrated a triumphant re-election victory in October. After his death on March 5, authorities announced new elections to select his successor. Who's running to replace Chavez? Nicolas Maduro, 50, is a candidate for the United Socialist Party of Venezuela. Henrique Capriles Radonski, 40, represents a coalition of opposition parties.
