What happened

Lula ended his re-election push with a march through São Paulo. Organizers told Reuters about 150,000 people filled a two-kilometer stretch of Augusta Street. Speaking from a campaign vehicle, Lula called the vote a choice between “democracy and barbarism.” AFP said he told crowds he would win in the first round and “defeat the far right.”

Why it matters

Latin America’s largest democracy is choosing whether to keep Lula, 80, for another term or return the Bolsonaro movement to the presidency through Flávio, 45. Jair Bolsonaro, a close Trump ally, was sentenced to 27 years for attempting a coup after his 2022 election loss, AFP said. NPR reported that Flávio has pledged to pardon his father if elected. The next president is also expected to help shape Brazil’s Supreme Court and its ties with Washington.

What’s next

Sunday’s first-round count, whether either candidate clears 50%, and, if needed, the shape of an Oct. 25 runoff campaign.

More context

Brazilian President Luiz Inácio Lula da Silva and Sen. Flávio Bolsonaro wrapped up their campaigns Saturday ahead of Sunday’s first-round presidential election. Both said they expected to win. Recent polls still point to a tight race and a likely runoff on Oct. 25.

Flávio Bolsonaro, a right-wing senator and the eldest son of former President Jair Bolsonaro, held a motorcycle caravan through Santa Bárbara d’Oeste and Americana in São Paulo state, joined by São Paulo Gov. Tarcísio de Freitas, G1 reported, and later rallied in Rio de Janeiro, Reuters reported. He urged voters to turn out and said he was convinced of a first-round win. AFP quoted him telling supporters not to “vote in installments.” He was photographed holding a placard with his father’s image.

How the vote works: Twelve candidates are on the presidential ballot, AP said, but only Lula and Flávio Bolsonaro are widely seen as able to advance. If no one wins more than 50% of valid votes Sunday, the top two meet in a runoff on Oct. 25. About 160 million Brazilians are eligible to vote on electronic machines. Partial results are usually clear within hours after polls close.

What the polls say: A Datafolha survey published Oct. 1 put Lula at 42% and Flávio Bolsonaro at 38% in a first-round scenario, Reuters reported. In a simulated runoff it had Lula at 48% and Flávio at 45%, within the poll’s 2-point margin of error. A CNT/MDA poll released Saturday showed Lula at 47.8% and Flávio at 42.1% of valid votes in the first round. AFP said the two remain in a statistical tie for a runoff.

Other pressures: Flávio has made hardline security proposals a campaign centerpiece, including El Salvador-style megaprisons, AP said. Lula has stressed sovereignty and warned against U.S. meddling. AFP said President Trump is watching the race closely but has not endorsed Flávio. Separately, Flávio is under investigation over financing of a biopic about his father that was backed by jailed banker Daniel Vorcaro; NPR said he denies money-laundering allegations.
