The 2022 Brazilian presidential elections marked a pivotal moment in national democracy, characterized by controversy and significant shifts in public perception of visual culture. These elections not only served as a platform for political discourse but also intensified existing polarization within society. This paper endeavors to conduct a semiotic analysis of the impact of graphic design and visual culture on shaping political narratives, focusing on the visual elements employed by Lula da Silva’s campaigns and supporters in comparison to those of Jair Bolsonaro. The analysis delves into the aesthetic, semiotic, and sociocultural dimensions of design, elucidating its intricate relationship with politics and highlighting the crucial role of social media in constructing political discourses and shaping public opinion. Moreover, this article seeks to deepen our understanding of the nuanced messages conveyed through graphic design and visual culture, unraveling their underlying meanings and persuasive strategies. By examining how social media platforms influence political culture and contribute to the aesthetic divide between the right and left, the study provides concrete case studies illustrating how graphic design serves as a potent tool for political communication. Ultimately, this research contributes to a more comprehensive comprehension of the intricate interplay between political communication, graphic design, and visual culture in the context of contemporary democracies, shedding light on the complex dynamics that shape public discourse and political engagement.
