Brazil prepares for tightly contested presidential runoff between Lula and Flávio Bolsonaro

Nearly 160 million Brazilians are scheduled to vote on Sunday in a presidential runoff that will decide whether President Luiz Inácio Lula da Silva secures a fourth term or Senator Flávio Bolsonaro, son of former president Jair Bolsonaro, takes the country’s highest office. Polling stations open at 8 a.m. and close at 5 p.m. Brasilia time, with electronic voting expected to deliver results the same night. Voting is compulsory for citizens aged 18 to 70, optional for those over 70 and for 16‑ and 17‑year‑olds. Runoff contests for governors are also being held in six states.

The first round on 4 October saw Bolsonaro ahead with 47.03 % of the vote to Lula’s 45.16 %, a margin of roughly 2.2 million votes that defied earlier expectations. Since the return to direct presidential elections in 1989, no candidate who finished second in the first round has ever won the presidency, underscoring the significance of the upcoming ballot. Both campaigns are now targeting the estimated 33 million voters who abstained in the first round.

Background

Lula, 80, leads the Workers’ Party and previously served as Brazil’s 35th and 39th president, holding office from 2003‑2010 and again since 2023. His tenure has been marked by economic growth driven by a commodities boom and the Bolsa Família cash‑transfer programme, which lifted millions out of poverty. He survived a year‑long imprisonment on corruption convictions that were later annulled, and his current term has seen a decline in approval ratings to as low as 24 % amid concerns over crime and the cost of living.

Flávio Bolsonaro, 45, represents the Liberal Party and enjoys the backing of most of the Brazilian right. He is campaigning on security, reducing public spending while preserving social programmes, and pledging to pardon his father, who is serving a 27‑year sentence for attempting a coup after the 2022 election. Bolsonaro has also announced a constitutional reform aimed at “re‑democratising Brazil,” according to El País. The Liberal Party recently secured its largest ever bloc in the Chamber of Deputies, meaning the runoff winner will govern alongside a supportive Congress.

Both candidates have accused Meta of unequal treatment on its platforms, adding a legal dispute to the already heated campaign. Internationally, Argentine President Javier Milei has endorsed Bolsonaro and accused Lula of attempting to “steal” the election, while Lula has used Milei’s intervention as a critique of his opponent.

Why it matters

The runoff will determine Brazil’s domestic policy direction and its relationship with the United States. Bolsonaro’s camp positions the election as a chance to align Brazil more closely with the US, especially given the former president’s ties to former US President Donald Trump. Lula, by contrast, argues that his administration will continue to share the benefits of Brazil’s rare‑mineral extraction and maintain social programmes such as an increased Bolsa Família payment by 15 %.

Economic stakes are high for the country’s 212 million residents, as the winner will oversee the world’s largest economy in South America for the next four years. Lula’s recent measures include cutting fuel taxes, pardoning debts of 3.6 million small businesses, and proposing a reduction of the maximum workweek from 44 to 40 hours. Bolsonaro’s promises focus on cutting public spending, maintaining security initiatives, and delivering a constitutional reform.

The outcome also has implications for Brazil’s legislative agenda. With the Liberal Party holding a historic bloc in the lower house, a Bolsonaro victory could facilitate the passage of right‑leaning reforms, while a Lula win would require negotiation with a Congress that is less uniformly supportive of his platform.

What happens next

Results are expected to be announced on the night of 27 October, once the electronic tally is completed. The newly elected president will assume office on 1 January 2027. Both campaigns have pledged to respect the outcome, though they have each warned of potential legal challenges should irregularities arise. International observers from regional bodies are slated to monitor the vote, reflecting the election’s significance for Latin American politics.

The runoff marks the culmination of a fiercely contested campaign, with both sides mobilising millions of supporters in the final days. As Brazil heads to the polls, the nation—and the broader region—awaits a decision that will shape its political and economic trajectory for the foreseeable future.
