Venezuela Denies 'Manipulating' Voter Turnout Number by VOA News Venezuela's election chief denies claims by a voting technology firm that voter turnout numbers for last Sunday's election on rewriting the constitution were "manipulated" by at least 1 million voters. The head of the National Election Council, Tibisay Lucena, calls the claim "irresponsible" and says Venezuela has the right to sue the firm. "This is an unprecedented opinion from a firm whose only role in the electoral process is to provide certain services and technical support that has no bearing on the results," she said. But the head of British firm Smartmatic, Antonio Mugica, said in London on Wednesday that there is no question in his mind that the numbers were inflated. "Based on the robustness of our system, we know, without any doubt, that the turnout of the recent election for a National Constituent Assembly was manipulated. We estimate the difference between the actual participation and the one announced by authorities was at least 1 million." He did not say whether the tampering changed the results of the election. The government said more than 8 million people cast ballots Sunday. The opposition, which boycotted the vote, said the turnout was less than half that number. Reporters in Caracas said dozens of polling places were almost deserted. The president of the opposition-controlled National Assembly, Julio Borges, said Smartmatic's findings are "complete confirmation" of what the opposition and election analysts had suspected. Pre-election polls showed more than 70 percent of all Venezuelans opposed a body to change the constitution. The opposition contends the vote was rigged to pack the assembly with supporters of President Nicolas Maduro. Maduro's opponents are demanding early presidential elections. The next scheduled election is October 2018. Lawmakers request investigation Borges said lawmakers will ask the country's top prosecutor to investigate members of the National Election Council for potential crimes. Despite the controversy surrounding voter turnout and the final results, Maduro plans to swear in the 545 members of the assembly so they can get to work Thursday. Details on what might be included in a new constitution are unclear. Maduro has said it is the only way to pull Venezuela out of its severe economic crisis and stop the daily protests that have killed more than 120 since April. But the opposition says its goal is to dissolve the opposition-controlled national assembly, fire anyone who disagrees with the government, and turn Venezuela into a socialist dictatorship. The United States, Canada, European Union, and nearly every Latin American nation have said they will not recognize the constituent assembly. The U.S. imposed sanctions against Maduro on Monday for what it called his "illegitimate" election of a body to rewrite the constitution. All of Maduro's assets in the United States are frozen and Americans are forbidden from doing any business with him. Maduro raged on television that he does not care. "They don't intimidate me. The threats and sanctions of the empire don't intimidate me for a moment. ... Bring on more sanctions, Donald Trump." 'Collapse into dictatorship' U.S. Vice President Mike Pence said Wednesday during a visit to Montenegro, "we've seen the completion of Venezuela's collapse into dictatorship. The United States calls on all who cherish freedom to condemn the Maduro regime for its abuse of power and its abuse of its own people." Pence reminded Maduro that he is "personally responsible" for the health and safety of opposition leaders Leopoldo Lopez and Antonio Ledezma, who were dragged out of their homes in the middle of the night earlier this week and taken to military prison. The Supreme Court accuses the two of breaking the terms of their house arrest for previous opposition activities and planning to flee the country. Lopez's lawyer denies the charges. The drop in global energy prices and political corruption have destroyed Venezuela's oil-rich economy. Gasoline, medicine and such basic staples as cooking oil, flour and sugar are scarce, and many Venezuelans cross into neighboring Colombia and Brazil to buy food. Maduro has blamed the country's woes on what he calls U.S. imperialism and its supporters inside Venezuela. He has warned against intervention by the Organization of American States, saying that would surely lead to civil war.
