Brazilian President Luiz Inacio Lula da Silva held a two-percentage-point lead over Senator Flavio Bolsonaro in a simulated runoff ahead of October’s presidential election, according to a Datafolha poll released Thursday. Lula received 47% support versus 45% for Bolsonaro, a technical tie because the result falls within the poll’s 2-percentage-point margin of error. The previous Datafolha survey showed Lula leading 46% to 44%. In a first-round scenario, Lula led with 40%, followed by Bolsonaro at 36%, Augusto Cury at 5%, Ronaldo Caiado at 4% and Renan Santos at 3%. Lula is seeking a fourth nonconsecutive presidential term. Flavio Bolsonaro is the eldest son of former President Jair Bolsonaro, who is serving a 27-year prison sentence for attempting to overturn his 2022 election defeat to Lula. Datafolha surveyed 2,002 people on Sept. 22 and 23. Other recent polls showed a closely contested runoff, with Quaest giving Bolsonaro a 42%-41% lead and BTG Pactual/Nexus putting Lula ahead 46%-45%.
