Quick Summary

Brazilians are voting in a general election where incumbent left-wing leader Luiz Inácio Lula da Silva faces right-winger Flávio Bolsonaro. Jair Bolsonaro, Flávio's father and former president, is barred from running due to his 27-year sentence for plotting a coup but remains influential through AI-generated endorsements. Polls show both Lula and Flávio around the 40% mark, with an October run-off likely if no candidate reaches 50%. Approximately 9% of voters remain undecided or plan not to vote, complicating predictions.
