Senator Flavio Bolsonaro is in a statistical tie with President Luiz Inacio Lula da Silva ahead of Brazil's October presidential election, with a September 24 Datafolha poll showing Lula at 47 percent and Flavio at 45 percent. The Bolsonaro family's electoral strength is driven by 'antipetismo' — hostility toward Lula's Workers' Party — rather than a hardcore base, which analysts estimate at 15 to 25 percent of the electorate.

Electoral Standing

Senator Flavio Bolsonaro, 45, is the leading right-wing contender in Brazil's October presidential election. He is in a statistical tie with incumbent President Luiz Inacio Lula da Silva, according to a September 24 Datafolha poll. The poll shows Lula with 47 percent support to Flavio's 45 percent in a simulated run-off, within the margin of error. Other pollsters predict an even narrower gap between the two frontrunners.

Family Legal Battles

Former President Jair Bolsonaro was sentenced to 27 years in prison for attempting to overturn his 2022 election defeat. In 2023, he was barred from holding public office for eight years after a court determined he abused his political office. He is currently banned from using social media, with his last post published in July 2025. Like his father, Flavio Bolsonaro has faced investigation and scandal.

Antipetismo Factor

Political scientist Paulo Roberto Souza of the Democracy in Check Institute said there is a hyperfocus on Lula and the PT, branded by many conservatives as solely responsible for rampant corruption. Analysts told Al Jazeera that the Bolsonaro family's electoral strength does not come from a base of hardcore supporters. Bolsonaristas are estimated to comprise between 15 and 25 percent of Brazil's electorate. Experts credit 'antipetismo' — hostility against Lula's PT movement — with fuelling the Bolsonaro family's rise to political power. The PT has won all but one of the last six presidential elections in Brazil.
