Brazil's October presidential election has stopped looking like a formality. President Luiz Inácio Lula da Silva entered the year with a comfortable path to a fourth term; six weeks out, pollsters are calling it a genuine contest, with Senator Flávio Bolsonaro — the eldest son of jailed former president Jair Bolsonaro — narrowing the distance week over week.
A Candidacy That's No Longer Speculation
Flávio's run stopped being a rumor back in July. The Liberal Party formally nominated him at a national convention held at São Paulo's Pacaembu stadium on July 25, and days later confirmed federal deputy Alfredo Gaspar as his running mate, with Flávio carrying ballot number 22 into his first presidential bid. His father can't appear on that ballot: Jair Bolsonaro was barred from running until 2030 and was sentenced last September to more than 27 years for a plot to overturn the 2022 election he lost to Lula. The elder Bolsonaro's custody status has shifted repeatedly over the past year — house arrest, then a stint in Federal Police custody after tampering with his ankle monitor, then humanitarian house arrest again in March 2026 for health reasons — and, per the most recent reporting, he remains under house arrest today.
Two Polls, One Story: A Dead Heat
The numbers back up the tightening narrative. A Quaest survey fielded August 30 to September 1 put Lula at 37% and Flávio at 30% in a first-round scenario, with undecided voters falling from 51% in mid-August to 42% once the official campaign period opened. Days later, a Datafolha poll fielded September 1–3 found a similar shape — Lula 38%, Flávio 32% — and, more strikingly, a runoff scenario where Lula's edge has shrunk to just two points, 46% to 44%. That's down from the four-point spread Datafolha measured in mid-August, when it had Lula ahead 47% to 43%. Other pollsters have shown the runoff gap bouncing between two and five points over the summer, but the direction is consistent: a race compressing as the October 4 first round approaches, with an October 25 runoff increasingly likely.
An Economy That's Losing Momentum
Part of what's lifting Flávio is timing: Brazil's economy is cooling right as voters head to the polls. Second-quarter growth came in at 0.5% quarter-over-quarter, propped up almost entirely by agriculture's 2.8% expansion while services and industry barely moved. The Central Bank's weekly Focus survey now pegs full-year 2026 growth near 1.9% — hardly the number an incumbent wants heading into an election. Inflation is still running above the official target, and the benchmark Selic rate, though trimmed from 15% to 14% through a cutting cycle that began in March, remains high enough to keep credit expensive. The OECD projects growth slowing further, to 1.6% this year, before a rebound in 2027.
Trump's Tariffs Become a Campaign Weapon
Layered on top of the slowdown is a trade rupture with Washington that's now inseparable from the campaign itself. Trump first threatened Brazil with a 50% tariff in July 2025, explicitly tying the move to his objections over Jair Bolsonaro's prosecution and calling the trial a "witch hunt." Washington later exempted coffee and beef from that levy, but in mid-July this year opened a new front: a separate 25% tariff on a broad range of Brazilian goods, which took effect July 22, again sparing coffee, beef and a handful of other categories. Flávio himself lobbied for relief, sending Washington a request to delay the new tariff by 180 days until after Brazil's election settles the country's political direction — an appeal that went nowhere, since the tariff took effect on schedule. Lula's campaign has used the episode to portray his rival as courting a foreign leader's interference in a sovereign vote.
Milei Wades In, and Brasília Pushes Back
Argentina's Javier Milei has amplified that framing from the other direction. He flew to São Paulo for Flávio's nominating convention, calling Lula a "thief" and a "convict" from the stage and casting Flávio as the candidate who could extend a string of right-wing victories across Argentina, Chile, Bolivia, Peru and Colombia into Brazil. The remarks — which also targeted Supreme Court Justice Alexandre de Moraes — were sharp enough that Brazil's foreign ministry recalled its own ambassador from Buenos Aires for consultations, deepening a bilateral rift that shows no sign of healing before the vote.
Why It Resonates With Brazilians in the U.S.
For the roughly two million Brazilians living in the United States — Itamaraty's most recent consular estimate puts the figure at 2.1 million, the largest Brazilian community outside Brazil — the stakes go beyond ideology. A large share is concentrated in Florida, while Newark's Ironbound neighborhood in New Jersey, built up largely by migrants from Governador Valadares in Minas Gerais, remains one of the country's most visible Brazilian enclaves. Families in both places depend on remittances flowing in both directions, and a prolonged tariff standoff threatens the small import businesses, restaurants and money-transfer shops anchoring those communities. Overseas voter rolls have also hit a record this cycle: nearly 919,000 Brazilians are registered to vote abroad, up almost 32% from 2022, with the United States — concentrated in Boston, Miami and New York — the single largest bloc.
What Comes Next
With just over a month before the first round, both campaigns are racing to lock down the shrinking pool of undecided voters, while Washington and Buenos Aires show every sign of staying involved in a race Brazilian officials increasingly describe as a proxy fight over the hemisphere's political direction.
