QUITO, Ecuador (AP) — The hand-picked candidate of socialist President Rafael Correa headed to victory in the opening round of Ecuador's presidential election, although it was uncertain early Monday whether he would get enough votes to avoid a runoff against his nearest rival. With more than 81.4 percent of polling stations reporting early Monday, ruling party candidate Lenin Moreno had almost 39 percent of the votes, compared to just under 29 percent for former banker Guillermo Lasso, the closest contender among seven opposition candidates. Moreno urged voters to uphold Correa's "Citizens' Revolution," while his challengers vowed to eliminate taxes they contend hamper growth and to strengthen democratic institutions they say were weakened by Correa's leadership. In the final weeks before the election, corruption allegations involving Moreno's running mate, current Vice President Jorge Glas, dominated airwaves. A leaked video widely shared on social media shows a disgraced former Cabinet minister undergoing a lie detector test and accusing Glas of taking some of the $12 million in bribes paid to state-run PetroEcuador for construction of a refinery.
