Brazil's runoff election remains too close to call between Lula and Bolsonaro's son

Brazil holds its presidential runoff this Sunday, with polls showing Luiz Inácio Lula da Silva and Jair Bolsonaro's son in a technical tie, though the far-right candidate holds a slight vote advantage and historical momentum after leading the first round. On October 5, Bolsonaro's son won 47.03% of votes versus Lula's 45.16%, a record-narrow margin of 2.225 million votes. Lula's campaign has united democratic sectors to attempt an unprecedented comeback, while facing entrenched polarization since 2018 and a Congress with extremist majorities if his rival wins. A Bolsonaro victory would align Brazil with Trumpism, potentially threatening democratic institutions through proposed constitutional reforms and judicial impeachments. Lula's campaign has mobilized street protests and a 10.7-million-member WhatsApp network, while alleging digital platform bias favoring the far-right, including AI tools refusing to generate pro-Lula content.
