Bolsonaro leads Lula into a 25 October runoff after 47 percent in the first round

Brazil's presidential election is going to a runoff on 25 October. With 99.89 percent of sections counted, the Superior Electoral Court gave Senator Flávio Bolsonaro of the Liberal Party 56,077,637 votes, or 47.05 percent of valid ballots. President Luiz Inácio Lula da Silva of the Workers' Party had 53,785,199 votes, or 45.13 percent. The gap is 2,292,438 votes. Neither man cleared 50 percent, so the constitution sends the pair to a second round.

A later Senate bulletin, with 99.97 percent counted, put Bolsonaro at 47.04 percent and 56,098,457 votes, and Lula at 45.15 percent and 53,846,396 votes. Turnout was 78.92 percent of registered voters. Abstention was 21.08 percent. Blank ballots were 1.84 percent and null ballots 2.93 percent.

Third place went to the writer Augusto Cury of Avante, with about 2.89 percent and 3,447,885 votes. Renan Santos of Missão took about 2.24 to 2.25 percent, or 2,675,584 votes. Ronaldo Caiado of the PSD took 2.18 percent. Those shares are too small to win. They are large enough to matter on 25 October if their voters move as a bloc.

The map repeats 2022. Lula led in all nine northeastern states. His strongest shares were in Piauí at 70.97 percent, Bahia at 66.09 percent and Maranhão at 63.94 percent. Bolsonaro led in 15 states, concentrated in the South, Southeast and Centre-West. BBC reporting placed Lula's support among lower-income voters, Catholics and women, and Bolsonaro's among wealthier voters and evangelical Christians in the south.

Flávio Nantes Bolsonaro is 45. He is a senator for Rio de Janeiro, with a term running from 2019 to 2026, and he chairs the Senate public security committee. This is his first presidential race. His father, Jair Bolsonaro, is serving a 27-year sentence for masterminding a failed coup after the 2022 defeat, and is barred from running. He endorsed his eldest son. Michelle Bolsonaro was elected to the Senate on the same night. Flávio has promised amnesty for his father and for supporters tied to the 8 January 2023 riots in Brasília. He has also promised to label gangs as terrorists, build maximum-security prisons, set a public-debt ceiling, cut spending, revise social welfare and expand the critical-minerals sector.

Lula called the first-round result unexpected. He said the game was about to start, that the campaign was in extra time, and that he would win over the Brazilian people in that extra time. Pre-election polling had him slightly ahead. The count reversed that order by about two points.

Congress moved with the Liberal Party. The PL elected the most governors, senators and federal deputies, and is expected to hold the largest bloc in the new legislature. A Bolsonaro presidency would meet a friendly chamber. A Lula presidency would meet a chamber his party does not control. Either way, the runoff does not settle the budget or the amnesty bill by itself.

The second round is three weeks away. Brazilian runoffs have narrowed and widened in that window before. The unused votes sit mainly with Cury, Santos and Caiado, a mix of a self-help writer, a new-party candidate and a centre-right governor-turned-candidate. Caiado's voters are the clearest fit for Bolsonaro. Cury's are not. Lula's path is to peel some of that remainder and to raise turnout in the Northeast, where his margins are already large. Bolsonaro's path is to hold the South and Southeast and to collect the right-wing remainder. The first-round lead is his. The majority is not.

The institutional setting matters as much as the head-to-head. Lula is seeking another term after returning to the presidency in 2023. Flávio would be the first son of a former president to win the office in this cycle, and he would do it while his father is in prison. An amnesty bill, if he wins and if Congress passes one, would reopen the 8 January cases and the conviction that kept Jair Bolsonaro off the ballot. That is a legal fight, not a slogan. The Superior Electoral Court and the Supreme Court have already set the boundaries of the ban. A new president cannot erase those rulings by inauguration speech.

State races moved the same way as the presidential map in several large states. The Liberal Party and the PSD came out ahead in the gubernatorial field, according to the first-night counts. A friendly governor does not deliver presidential votes automatically. It does shape police, state budgets and the local machine that turns voters out on 25 October. In the Northeast, Workers' Party governors remain the counterweight.

Money and programme differences are already on the table. Bolsonaro's debt-ceiling pledge and welfare revision would land on a Congress his party expects to lead. Lula's case to the same Congress, if he wins, is continuity of social transfers and a foreign policy that has kept Brazil in talks with both Washington and Beijing. Neither programme was tested in the first round beyond the two-point gap. The gap is the fact. The runoff is the test.
