This study analyzes political polarization in Argentina (2019, 2023) and Brazil (2018, 2022) during presidential campaigns, focusing on the interaction between political actors, media, and key themes on digital platforms. Over 1.5 million public Facebook posts were collected via CrowdTangle. Techniques like LDA and co-occurrence graphs revealed significant differences. In Argentina, narratives were dominated by economic and political issues, with strong anti-establishment discourses from figures like Javier Milei. In Brazil, polarization revolved around religious values and institutional legitimacy, with evangelical actors playing central roles. These findings highlight how national contexts shape digital dynamics, amplifying specific discourses and actors during electoral periods.
