Lula, Bolsonaro Clash as Brazil Heads to Tight Runoff

Thirty-three million Brazilians skipped the first round of the presidential election on October 4. That amounts to about one in five eligible voters, the highest first-round abstention rate since 1998. Six days before the runoff, the two men seeking their votes spent roughly two hours on Sunday night calling each other liars.

President Luiz Inácio Lula da Silva and Senator Flávio Bolsonaro faced each other for the first time in a debate on Band TV in São Paulo on October 18. Journalists Adriana Araújo and Eduardo Oinegue moderated three blocks, including 30 minutes of open exchange. The debate covered debt, food prices, public spending, public security and healthcare. Analysts expected the candidates to court undecided voters. That didn't happen. They traded remarks about family members, at times spoke inaudibly and offered little about their plans for the future.

A Contest of Insults

Lula called Bolsonaro "a habitual liar," a "thug" and a "militiaman," referring to alleged ties to Rio de Janeiro paramilitary groups. Bolsonaro said he preferred to keep Lula at a distance "because my wallet could be stolen." As Lula spoke, Bolsonaro paced behind him, shaking his head and smirking. The moderator intervened when a disturbance broke out in the audience just as Lula began his closing statement.

Lula, of the Workers' Party, cited his economic record. He said Brazil earned two investment-grade credit ratings during his administrations and is close to regaining that status. He said Brazil repaid a US$30 billion debt to the International Monetary Fund and now has US$270 billion in reserves. He argued that distributing money across households drives growth, and said his model has produced the largest social inclusion programme in the country's history.

Bolsonaro, of the Liberal Party, put the focus on the cost of living, debt and crime. He asked viewers how long it had been since they put meat in the freezer. He called public debt of R$11 trillion, about US$2.2 trillion, a "negative record." He pledged to free more than R$200 billion in the federal budget to pay down debt, and proposed that the state buy debts from banks and freeze payments. Correio Braziliense reported that the freeze would last six months for individuals and one year for companies.

Lula asked how deep Bolsonaro's cuts would go, and whether he would "borrow Milei's chainsaw," referring to Argentine President Javier Milei's spending reductions. Bolsonaro didn't answer the question directly. Lula also asked if Bolsonaro would hand Brazil's natural resources to the United States and accused him of planning to privatise Petrobras.

Who Knows the World of Work

The sharpest exchange on living standards focused on labour. Flávio said he had changed his mind about ending the 6×1 work schedule—six days of work followed by one day of rest—after listening to voters. Lula said Flávio had never worked a regular job and didn't know the world of work. "My opponent only knows about buses from books," Lula said. "He has never even stepped foot on one."

Flávio conceded ground on the pandemic. "This wasn't an area where we saw the best results during Bolsonaro's presidency," he said. "I'll offer a mea culpa here."

Investigations and Fact-Checks

Corruption allegations hung over both men. Flávio began by attacking Lula over an alleged influence-peddling case involving Lula's eldest son, Fábio Luís Lula da Silva. Lula answered by pointing to investigations into Flávio, including one linked to Banco Master. On Sunday, Brazil's federal police asked the Supreme Court to open an investigation into Flávio over a money-laundering accusation involving a lawyer close to him. Authorities were already investigating his links to Daniel Vorcaro, a disgraced former banker who financed a film about Jair Bolsonaro's life. Flávio denied wrongdoing in both cases.

Lula challenged Flávio to open their personal finances to scrutiny before the runoff. He also demanded an explanation about a corruption investigation involving the elder Bolsonaro. Flávio dodged the question and raised a possible case involving one of Lula's sons.

Fact-checkers at Folha de S.Paulo found errors on both sides. Flávio said trips by Lula and first lady Rosângela "Janja" Lula da Silva cost R$7 billion. Folha said that figure included federal travel by many government bodies, not trips by the couple. Aos Fatos reported that the Presidency itself spent R$150.5 million on travel from 2023 to 2025. Lula said GDP didn't grow by more than 3% a year between 2010 and 2023. Folha called that wrong, citing growth of 4% in 2011 and 4.8% in 2021.

Folha also corrected Flávio about his father. Flávio said Jair Bolsonaro couldn't vote because he was a victim of persecution. The reason is legal: Brazil suspends political rights after a final criminal conviction. Band reported the conviction was certified on November 25, 2025, with a sentence of 27 years and three months, tied to efforts to overturn the 2022 election Bolsonaro lost to Lula. Lula said Flávio "took" R$134 million from Vorcaro. Folha said Flávio asked directly for the money, but received only part of it, at least R$60 million. Flávio said it was private sponsorship for the film Dark Horse, with no public money involved.

A Race Within the Margin of Error

Flávio won the first round with 47.03% to Lula's 45.16%. A BTG Pactual/Nexus poll released October 19 put Flávio at 50.3% and Lula at 49.7% of valid votes, a gap well inside the 2-point margin of error. The poll interviewed 2,002 voters from October 16 to 18, so it didn't capture the debate's full effect. An earlier survey had Flávio at 52% to 48%. Lula's approval rose 1.9 points to 47.2%, while disapproval stood at 48.8%.

Voters told the Associated Press that corruption was wearing them down. José Tainan, a 36-year-old kitchen assistant from Rio's Penha complex of favelas, said it was why he stopped voting. "There are no good options," he said. "I would rather justify why I didn't vote." Camila Tobji de Aquino, a 19-year-old student, said she saw Flávio as a threat to democracy. "If I were to vote only for a candidate not tied to any corruption, I would vote blank," she said. "But that's not the choice Brazil is facing. For me it's a question of being able to vote in the next election."

Taxi driver Matusalem Aguiar, 54, from Belford Roxo, said he would overlook the investigations and vote for Bolsonaro. "There needs to be a change," he said.

Experts said corruption may affect turnout more than candidate choice. Laura Chelidonopoulos, a political science PhD candidate at the University of Pittsburgh, said repeated scandals can disillusion voters: "People become disenchanted with politics. They have less motivation to actually choose between one of these two sides." Nara Pavão of the Federal University of Pernambuco said: "People don't want to discover the truth about their candidates, they want to beat the opponent." Bolsonaro received 2.2 million more votes than Lula in the first round. TV Globo will host a second debate on Friday, October 23.

Why This Matters: Brazil's runoff on October 25 will depend as much on who shows up as on who persuades voters. Voting is mandatory for citizens aged 18 to 70, yet 21% of the electorate stayed home in the first round, and experts warn that scandal fatigue may push that number higher. A debate full of insults instead of plans offers little to voters worried about food prices, debt and public safety. The stakes extend beyond one term. Jair Bolsonaro is in prison serving a sentence tied to efforts to overturn the 2022 election, and some voters say the question is whether democratic institutions hold. Fact-checks matter too. Both candidates stretched numbers, and citizens who rely on public services need accurate figures to judge who will protect them.
