The University of Lisbon will receive 78,833 Brazilian voters on Sunday (4), making it the largest voting location outside Brazil. The number exceeds that of Boston, second place, by 25 thousand, and reflects the 74% increase in registered voters in Lisbon since 2022. Ambassador Alessandro Candeas explains that the community in Portugal remains more connected to Brazil, while the consulates in New York, Boston and Miami, although larger in terms of population served, have lower electoral engagement. Voting will take place in three university buildings using QR Codes and support staff to avoid queues like in 2022, when waiting times reached five hours. Militants of Lula and Flávio Bolsonaro adopt different strategies, with PT members organizing demonstrations in Rossio and Bolsonaro supporters acting through videos and online events. The consulate estimates that between 700,000 and 1 million Brazilians live in Portugal, far beyond the 574,195 registered by INE.

Senator Flávio Bolsonaro ended the campaign for the first round of the presidential elections with a motorcade in the west zone of Rio de Janeiro, ending at Praça da Fé in Bangu, where the Catholic church closed its doors due to the noise of the political event with jingles and fireworks. The senator did not speak to the press and was accompanied by allies such as Douglas Ruas, PL candidate for governor of Rio. During the 13 km route between Campo Grande and Bangu, there were verbal confrontations with supporters of the PT candidate Adilson Pires, who called Flávio a 'thief', while Bolsonaro supporters responded to the provocations without physical aggression. Ruas said he hoped to win the state dispute against Eduardo Paes and criticized Lula, calling him an 'expired product', after the TSE annulled Anthony Garotinho's votes.
