Brazil votes for president on October 4, and for months the contest looked like it would settle into a straight fight between President Luiz Inácio Lula da Silva and Senator Flávio Bolsonaro. That basic shape hasn't changed. What has changed is how lopsided it now looks — and the reason traces back to a single leaked recording about a movie that was never supposed to become a political liability.
Lula's Bid for a Fourth Term
Lula, who turned 80 in October 2025, is running for what would be an unprecedented fourth presidential term, again alongside Vice President Geraldo Alckmin, whose spot on the ticket was locked in on March 31. He has topped every first-round poll released this year, generally scoring somewhere in the high 30s to low 40s, with one mid-July survey putting him at 40 percent nationally and as high as 47 percent in a head-to-head runoff simulation against Flávio. His pitch to voters rests heavily on expanded welfare spending, a large stimulus package, and a tripled advertising budget — the kind of incumbency muscle that becomes illegal to flex once campaign rules kick in, which happened on July 4. Inflation and a swelling public debt remain his most obvious vulnerabilities.
The Chosen Heir Under Siege
Flávio Bolsonaro, a 45-year-old senator from Rio de Janeiro, secured his father's blessing in December after visiting him at the house-arrest residence where the former president is serving his sentence — a nod that functioned, as Al Jazeera reported, as a coronation rather than the product of any internal primary. For a stretch in the spring he looked like genuine frontrunner material, closing a runoff gap that had once run past 20 points and briefly edging ahead of Lula in isolated polls. Then May happened, and the momentum reversed hard — more on that below.
The Governors Who Wouldn't Wait Their Turn
Two sitting governors gave up their offices this year to chase the presidency as alternatives to the Bolsonaro name. Ronaldo Caiado of Goiás, a rancher and physician with deep ties to agribusiness and evangelical voters, switched to the PSD and became its nominee after outflanking two rival governors in his own party caucus. Romeu Zema of Minas Gerais, a businessman running on free-market credentials for the NOVO party, has stayed in the race despite consistently polling in the single digits. Neither man threatens to win the first round outright, but both do noticeably better than their national numbers suggest whenever pollsters test them head-to-head against Lula — a sign that some anti-Lula voters simply don't want the Bolsonaro surname on their ballot. Caiado has been the more aggressive of the two, telling Jovem Pan in June that the polling numbers themselves show Flávio "has lost the ability to beat" Lula, and positioning his own candidacy as the more viable conservative option.
Renan Santos and the Fight for Young Voters
The field's most interesting new entrant is Renan Santos, the 42-year-old co-founder of the Free Brazil Movement, now running under his own newly registered Missão party. Nationally he barely clears mid-single digits, but among Brazil's youngest voters he's a phenomenon: an AtlasIntel survey from May had him pulling in 36 percent of voters aged 16 to 24, ahead of both Lula and Flávio in that bracket, even as roughly three-quarters of the broader electorate say they don't know who he is. His pitch is deliberately anti-establishment and anti-both-dynasties, and his standing in prediction markets climbed noticeably through late May and early June as the Vorcaro scandal made an "anti-corruption outsider" pitch more resonant.
The Long Tail of the Ballot
Rounding out the field are several candidates who rarely crack 2 percent nationally: Augusto Cury, a bestselling psychiatrist-author running for the Avante party; Cabo Daciolo, a former federal deputy and 2018 presidential candidate now representing the small Mobiliza (National Mobilization) party; and Aldo Rebelo, whose Christian Democracy candidacy has been complicated by a legal dispute over his own party registration. The only woman in the presidential field so far is Samara Martins, a 38-year-old dentist and national vice president of Unidade Popular — a small socialist party, distinct from the similarly named PSTU, whose own candidate this cycle is Hertz Dias.
Who Isn't Running, and Why That Matters
The empty chairs tell their own story. Jair Bolsonaro is barred from holding office until roughly 2030 under a 2023 electoral-court ruling, and separately began serving a 27-year prison sentence in November for orchestrating the plot to overturn his 2022 election loss. He's currently serving that sentence under house arrest rather than in custody: he was hospitalized in March with bronchopneumonia and worsening kidney function, and on July 3 Justice Alexandre de Moraes extended the house-arrest arrangement indefinitely despite an unrelated incident involving a firearm found with his security detail.
Tarcísio de Freitas, the São Paulo governor most analysts consider the right's strongest hypothetical candidate, chose to run for reelection instead and has repeatedly confirmed his backing of Flávio — a decision that, under Brazilian law, disqualifies him from the presidential race this cycle since he didn't resign the governorship in time. Pablo Marçal, the influencer who ran for São Paulo mayor in 2024, has been barred from politics until 2032 over abuse of economic and media power and illicit fundraising during that campaign. And in a quieter footnote, the PSDB floated a centrist bid built around former party leader Aécio Neves this spring; he turned it down, telling Estadão he saw the looming Lula-Flávio matchup as something closer to a family feud playing out on a national stage.
The Recording That Rewrote the Race
Until mid-May, this was a genuine coin-flip election. Multiple pollsters had shown Flávio numerically ahead of or tied with Lula in second-round simulations for the first time, and betting markets had him near his ceiling. Then on May 13, Intercept Brasil published leaked audio and messages showing Flávio had personally negotiated financing from Daniel Vorcaro — the jailed former owner of Banco Master, arrested weeks earlier over a fraud scheme that gutted Brazil's deposit-guarantee fund — to help pay for a biographical film about his father. The messages show Vorcaro had committed to funneling roughly $24 million (R$134 million) toward the production, of which documented transfers show at least $10.6 million had already moved before his arrest. Flávio has acknowledged the contact but denies any wrongdoing, insisting it was private sponsorship of a private film with zero public money involved.
The political fallout didn't fade the way scandals sometimes do. Flávio's first-round numbers slipped from the high 30s into the low-to-mid 30s over the following weeks, and his runoff deficit against Lula widened back out — June polling from Quaest and other houses had him trailing by high single digits, and a July 13 Nexus/BTG survey put Lula at 47 percent to Flávio's 44 in a technical tie that nonetheless kept the numeric edge with the president. Betting markets moved the same direction: Lula's implied odds on Polymarket climbed from roughly a coin flip in April into the mid-50s to low-60s range by early July, while Flávio's odds sank into the low-to-mid 20s.
Then came a second, unrelated blow. On June 16, Brazil's Supreme Court convicted Flávio's brother Eduardo Bolsonaro of pressuring the Trump administration to intervene in their father's coup case, sentencing him to four years and two months in prison and barring him from office for eight years. Some Brazilian outlets, including CNN Brasil, have reported the effective disqualification could stretch past 12 years once the calculation accounts for the ineligibility clock starting only after the prison term ends — which explains why the two figures show up in different places. Eduardo has argued the real goal of the case was simply to sideline him politically.
Cracks Inside the Family Brand
Days after Eduardo's conviction, Michelle Bolsonaro — the former first lady — stepped down as head of the Liberal Party's women's wing, a role she'd built since 2021. The resignation followed a public falling-out with her stepson over a dispute involving Senate alliances in Ceará, and it left the party without the figure most credited with softening its standing among women voters — a demographic where Lula already leads by double digits. Party president Valdemar Costa Neto acknowledged there's no obvious replacement.
Not every recent data point fits the narrative of one-way collapse, though. That same Nexus poll from July 13 still showed a technical tie rather than a rout, and undecided or blank-ballot voters have roughly doubled since spring — room for the race to move again before October. Caiado, Zema, and Renan Santos appear to be the scandal's main beneficiaries so far, picking up voters who've soured on Flávio but aren't ready to return to Lula either.
What Happens Between Now and October
Party conventions run from July 20 through August 5, when coalitions and tickets become official. Formal campaign advertising begins August 16, with free television and radio airtime specifically starting August 28. If no candidate clears 50 percent of the vote on October 4 — and every Brazilian presidential race since 2002 has required exactly that outcome — the top two finishers advance to an October 25 runoff.
