At the entrance to each voting station Venezuelan voters are required to confirm their identity on a machine that reads their thumbprint. According to several testimonies aired by local TV station Globovision, the lack of these thumb printing machines or their malfunctioning was causing many of the delays at voting stations.
Yet, in some parts of Caracas, voting seemed to run smoothly. Rosita Quintero, 55, volunteered at a voting center lodged in the Martinez Cedeño School in Caracas.
"There are some 2,700 people registered here, and by noon half of [those registered] had voted," Quintero told ABC/Univision.
At the nearby Cristo Rey School however, hundreds of people formed a massive queue, waiting for a chance to vote.
"This is the most exciting queue I've made in my life," said 26-year-old Paolo Prato, who said that she wanted a new government run by Capriles to tackle problems like high crime rates and unemployment.
Prato had to wait four hours to cast her ballot at the voting center, where more than half of registered voters had cast their ballots by 3pm.
"People are very happy here," she said. "I'd do this line two, three, four thousand times more."
