The purpose of this dissertation is to address the potential of populism in political organization or, more precisely, in the constitution of effective bodies. The paper presents the main concepts mobilized by Ernesto Laclau s theory of populism and, in a dialogue with authors such as Yannis Stavrakakis, John Protevi, Vittorio Morfino, Frédéric Lordon and Espinosa, aims to deepen the discussion about the affective aspects involved in the construction of a populist discourse, as well as investigating the possible relationship between the recent populist explosion, especially in the United States and Europe, and certain characteristics of so-called late capitalism.
