Brazil votes in polarizing runoff between Bolsonaro and Lula

On a Sunday morning in Rio de Janeiro, more than 120 million Brazilians lined up to vote in a presidential runoff that had cleaved the nation into opposing camps. The choice before them was stark: keep President Jair Bolsonaro in office, a far-right incumbent who framed his mission as defending Christian values and conservative social order, or return Luiz Inácio Lula da Silva to power, a former president who promised to restore the prosperity and social mobility of his earlier tenure from 2003 to 2010. Both men were household names, divisive figures who inspired devotion and revulsion in roughly equal measure.

The race had tightened considerably in the weeks leading up to the vote. When the first round of voting took place on October 2, Lula finished ahead with 48 percent of the vote, while Bolsonaro captured 43 percent among eleven candidates. That eight-point gap looked commanding on paper, but it masked a troubling reality for Lula's camp: the opinion polls had significantly overestimated his lead. Bolsonaro had proven far more popular than most analysts expected. He had secured endorsements from governors in Brazil's three most populous states, and his allied politicians had won substantial victories in congressional races. Political scientist Rodrigo Prando, a professor at Mackenzie Presbyterian University in São Paulo, acknowledged the paradox: mathematically, Lula remained ahead, but politically, Bolsonaro had grown stronger than anyone had imagined.

The stakes extended beyond the presidency. Twelve gubernatorial races were also being decided on the same day, including contests in São Paulo, Amazonas, and Bahia. More than 150 million Brazilians were eligible to cast ballots, though roughly one in five had abstained during the first round. Both campaigns had pushed hard on turnout, and the Supreme Court had ordered state capitals to provide free public transportation on election day to remove barriers to voting. The electronic voting system meant that results would arrive within hours of the polls closing in the late afternoon—no waiting, no suspense drawn out over days.

The campaign itself had been brutal. Bolsonaro attacked Lula's past relentlessly, reminding voters that Lula had been imprisoned for 19 months on corruption and money laundering charges. The Supreme Court had annulled those convictions in 2019, ruling that the judge had been biased and had colluded with prosecutors, but Bolsonaro weaponized the convictions anyway, warning that electing Lula would be like inviting a thief back to the scene of the crime. He also made sweeping claims without evidence that Lula's return would bring communism, legalized drugs, abortion, and persecution of churches. Lula countered by highlighting Bolsonaro's mishandling of the COVID-19 pandemic and his failure to protect the country's poorest citizens. He also attacked the president's environmental record, pointing to the dismantling of environmental enforcement agencies and the surge in deforestation that had followed. Lula also targeted what he called the "secret budget"—billions in government money directed to lawmakers for their pet projects in exchange for political support, a system so opaque that its true uses remained hidden. That money, Lula argued, had been stolen from social programs.

Yet Lula's own party carried baggage. The Workers' Party had been ensnared in sprawling corruption investigations that had implicated top politicians and executives in vast scandals. For many voters, that history was as troubling as anything Bolsonaro had done.

What worried observers most, however, was Bolsonaro's behavior in the final days before the vote. His campaign had begun circulating unproven claims about electoral manipulation. For months, he had alleged that Brazil's electronic voting machines were vulnerable to fraud, though he had never produced evidence, even after the electoral authority set a deadline for him to do so. More recently, his campaign had shifted tactics, claiming that radio stations had failed to broadcast more than 150,000 of his campaign advertisements and suggesting this was a deliberate effort to sabotage his candidacy. The electoral authority rejected the claim, saying there was no evidence to support an investigation. The pattern was unmistakable to observers: Bolsonaro was laying groundwork to contest the results if he lost, much as former U.S. President Donald Trump had done in 2020. Carlos Melo, a political science professor at Insper University in São Paulo, captured the anxiety: "We don't know whether this result will be contested or not, and to what extent. It's a very tough second round and a very tense Sunday, and tensions may continue beyond today." The vote would decide not just who led Brazil, but whether the loser would accept the outcome.
