The result of the referendum was not to recall Chávez (58% no), but there have been allegations of fraud. In 2004, a report by election observers rejected the hypothesis of fraud,[1][2] but statistical evaluations released in 2006[3] and 2011[4] disagreed. Former United States president Jimmy Carter[5] and his Carter Center,[6] all groups which had observed the referendum,[2] and other analyses[7] denied fraud, saying the referendum was performed in a free and fair manner, with Carter even accusing opposition-aligned sources of manipulating data.
