Brazil Heads to a Knife-Edge Runoff as Flávio Bolsonaro Edges Lula in First Round

BRASÍLIA — Brazil's presidential race will go to a second round after right-wing senator Flávio Bolsonaro finished narrowly ahead of incumbent President Luiz Inácio Lula da Silva in Sunday's first-round vote, defying pre-election surveys that had shown Lula leading by around three points.

With 99.96% of polling stations counted, the Superior Electoral Court (TSE) reported Flávio Bolsonaro, of the Liberal Party, at 47.04% (56.1 million votes) and Lula, of the Workers' Party, at 45.15% (53.8 million votes), a gap of about 2.25 million votes. Because neither candidate passed 50% of valid votes, the two will meet again in a runoff on Sunday, October 25.

Voters queued across Brazil's 27 states to cast ballots on the country's electronic voting machines.

The rest of the field

Augusto Cury (Avante) finished third with 2.89%, followed by Renan Santos (Missão) at 2.24% and Ronaldo Caiado (PSD) at 2.18%. Their combined share of roughly 7% now becomes the most contested prize of the campaign. Blank and null ballots totalled about 6 million.

A country split by region

The map showed a familiar divide. Lula swept all nine states of the Northeast, with his strongest showings in Piauí (71%) and Bahia (66%). Bolsonaro led in 15 states, including the three largest southeastern electorates: São Paulo (51.9%), Rio de Janeiro (53%) and Minas Gerais (48.2%), as well as the agricultural Centre-West and the South. Amapá was the closest state, with Lula ahead by only 225 votes.

Supporters filled streets in São Paulo and Brasília as results came in on Sunday night.

Reaction from both camps

Addressing supporters in Brasília, Flávio Bolsonaro, son of former president Jair Bolsonaro, said the result signalled "the end of an era" for the Workers' Party. Speaking in São Paulo, Lula called the outcome "unexpected" but insisted the race was not over. "We have just had a lesson in Brazilian democracy," he said, adding that his rival's record would become clearer to voters before the runoff.

In Washington, U.S. President Donald Trump described Bolsonaro's showing as a "very, very big victory" while predicting a "very close" final contest.

The Senate tilts right

Beyond the presidency, conservatives made major gains in Congress. Of the 54 Senate seats up for election, 34 went to candidates from the right or far right, a result that could constrain whoever wins the presidency. Prediction markets moved sharply toward Bolsonaro after the count, though analysts caution that Lula has come from behind before.

Brazil's electronic system allowed the TSE to report nearly complete results within hours of polls closing.

What comes next

The next three weeks will turn on two questions: whether Lula can win back voters in the populous Southeast, and where supporters of Cury, Santos and Caiado move. Economic concerns, security and Brazil's relationship with the United States are expected to dominate the final debates. The New Dispensation will bring full coverage of the October 25 runoff.
