This chapter argues that, through his construction of otherness, the populism of Mexican President Andrés Manuel López Obrador could be understood as a right-wing populism. This is because he develops a political communication strategy that seeks to eliminate from legitimate political participation those who are not part of the people he claims to represent. To develop this idea, the discursive elements of López Obrador's political project were identified through the theory of Ernesto Laclau. Then, we added a performative approach to include the concrete adjectives that the discourse associates with otherness and, with a semantic analysis using ATLAS.ti & OpenAI, we identify the performative signifiers that define his antagonistic other. These performative signifiers showed that the discourse seeks to exclude his adversaries from the democratic game.
