The Brazilian presidential election cycle has generated significant political activity and mobilization in South America. On October 4, over 11,000 Brazilian citizens gathered at the embassy in Buenos Aires to vote, an event marked by tension between supporters of Luiz Inácio Lula da Silva and Flávio Bolsonaro. During this period, a dual Argentine-Brazilian national was arrested in front of the mission following a confrontation with police over unauthorized merchandise.

By October 11, political mobilization increased. In São Paulo, approximately one million people gathered on Avenida Paulista to support Lula da Silva ahead of the second round of voting. This demonstration, organized by social movements and student unions, expressed opposition to far-right politics following a first round where Flávio Bolsonaro received 48.17% of the valid votes and Lula da Silva received 43.83%.
