The Comparison of Populist Discourses in Latin America, the Cases of Bolsonaro and Maduro, against the Principles of Liberal Democracy takes shape in the science and ideology of populism. This paper makes an exclusive step in analyzing the speeches of two populistic leaders: Nicholas Maduro, the President of Venezuela, and Jair Bolsonaro, the President of Brazil. In particular, the paper looks into the nature of speech directed to campaigns and the United Nations. Campaign speeches are generally the most difficult to locate since they were made before the politician was elected and thus are not often documented on any official website. The UN speech is considered an international speech because it has a significant or primary audience of common people, including diplomats. Examining Bolsonaro's speech is the first step in understanding what occurred in Brazil's contentious 2018 federal elections. Brazil may be an instance where demand for populism meets supply, but this can only be recognized by comparing populist supply with voter desire for populism, which necessitates the examination of public opinion data. On the other hand, addressing the speech that Bolsonaro directed to the UN concerning the Covid-19 pandemic and environmental conservation approaches enables us to understand his stance on health and the environment. Madura's speeches are constantly urging for the sovereignty of his country and people. He feels that sanctions put by the UN are detrimental to the people whom he swore to protect in his campaign. According to his belief, the UN should not impose sanctions upon the country's resources, such as national oil. Instead, his country's financial accounts are being pursued, gold has been confiscated and blocked from the Central Bank of Venezuela's lawful foreign reserves in London, and billions of dollars in bank accounts in the United States, Europe, and elsewhere have been seized and blocked. This is opposite to his populist ideology and opinion.
