Lula da Silva and Flávio Bolsonaro hold final rallies ahead of tight Brazilian presidential vote

Final campaign push in the southeast

On Saturday, Brazil's presidential candidates will hold their closing campaign events across the populous southeastern states of São Paulo and Rio de Janeiro ahead of Sunday's election. President Luiz Inácio Lula da Silva of the Workers' Party (PT) leads a rally through central São Paulo alongside Vice President Geraldo Alckmin and Senate candidates Marina Silva and Simone Tebet. Senator Flávio Bolsonaro of the Liberal Party (PL), the eldest son of former president Jair Bolsonaro, begins with a motorcade in the interior of São Paulo state before travelling to Rio de Janeiro in the afternoon. São Paulo Governor Tarcísio de Freitas accompanies Bolsonaro, advocating tactical voting among right-wing voters to consolidate support behind the senator. The three southeastern states of São Paulo, Minas Gerais, and Rio de Janeiro account for nearly 40% of the country's 158.7 million eligible voters.

Tight polling and runoff expectations

Polls released between 28 September and 2 October show an evenly matched race between the two leading candidates, with neither projected to win the absolute majority required to avoid a second round. A PoderData/Aya survey published Saturday places Lula at 45% of valid votes and Flávio Bolsonaro at 43%, within the 1.5 percentage point margin of error. Other surveys show similar margins, with Datafolha measuring 42% for Lula against 38% for Bolsonaro, AtlasIntel/Bloomberg showing 45.3% to 42.2%, and Quaest reporting 39% to 34%. Ten other candidates remain on the ballot, led by author Augusto Cury, former Goiás governor Ronaldo Caiado, Renan Santos, and Minas Gerais governor Romeu Zema.

Contrasting security and economic visions

The two frontrunners offer sharply opposing platforms for Brazil's administration, focusing on public safety and state spending. The 45-year-old Flávio Bolsonaro promotes reductions in state services alongside hardline anti-crime measures, including high-security prisons modeled after El Salvador, lowered age limits for criminal responsibility, and chemical castration for sex offenders. Bolsonaro framed his political identity during his nomination speech:

I can be calmer, smiling, more serene and moderate. But Bolsonaro's blood runs here.

The 80-year-old Lula advocates expanded social safety nets, public investment, and targeted operations against criminal financial networks. His administration expanded the Bolsa Família welfare program by 15% and announced state debt relief for indebted families, contributing to a broader 411.2 billion real (around 69.5 billion euros) social spending package calculated by Poder360. Brazil's gross public debt reached 93.3% of gross domestic product in 2025.

Legal controversies and international stakes

Scandals and legal proceedings surround both campaigns as voters prepare to choose federal and state representatives alongside the presidency. Flávio Bolsonaro faces federal police scrutiny concerning payments from Daniel Vorcaro, the former owner of Banco Master who is under investigation for financial crimes and corruption, regarding funding for the film Dark Horse. Former president Jair Bolsonaro remains incarcerated, serving a 27-year sentence handed down by the Supreme Federal Court for planning a coup attempt after the 2022 election. German Latin America expert Janek Bruno Werner assessed the broader consequences of the vote for European trade and diplomacy:

Brazil may be a twelve-hour flight from Germany, but how political conditions develop there has concrete effects on Germany.

If no presidential candidate captures over 50% of the valid votes on Sunday, the contest will advance to a head-to-head runoff on 25 October.
