The U.S., its allies, and citizens of Venezuela are demanding a recount after the elections granted Chavez' prodigy, Nicolas Maduro presidency.
CNN said the candidates were Nicolas Maduro and Henrique Capriles Radonski. Maduro won by a margin of less than 2 percent.
On the voting day in Venezuela, which was last Sunday, 79 percent of registered voters went to the polls. Maduro won by over 260,000 votes, or about 1.6 percent of the votes, the Huffington Post said.
In Venezuela a manual recount is impossible. In 1999, Veneuzelan Chief Justice Luisa Estella Morales eliminated manual recounts in favorite of a "system audit," CNN said.
The system audit is a completely automated counting device used in Venezuelan polls, CNN said.
The late President Hugo Chavez chose Maduro to be his successor before his death in March. This election divided Venezuela even further, because of the tight election results and the inability to do a recount, CNN said.
According to Venezuela's state-run news agency, eight people have been killed in violence due to the election results. The news agency also reported that 135 had been arrested because of the political violence, CNN said.
The Huffington Post said the U.S. isn't giving into the election results without a recount. They will not recognize the elections until the recount is done.
