Flávio Bolsonaro, carrying forward the legacy of his father and Brazil’s former conservative president, defeated radical socialist incumbent President Lula da Silva in the first round of the presidential race overnight Sunday. With 99% of votes counted, the gap between the two surged to more than 2.7 million votes in favor of Bolsonaro, who led confidently throughout the night despite a slight narrowing trend in the early stages.

Vote counting began immediately after the electronic ballot boxes closed under the supervision of the Supreme Electoral Court. Early on, Flávio Bolsonaro jumped above 50%, but as counting progressed and results flowed in from additional regions, the gap began to narrow.
Still, the final result reflects a dramatic turnaround: Bolsonaro took 47.23% of the vote—55,774,942 total—while the 80-year-old socialist, seeking a fourth non-consecutive term, had to settle for 44.92% with 53,111,936 votes. It’s a harsh blow for the incumbent president, as the right-wing opposition heads into the runoff with tremendous momentum and a clear advantage in absolute voter numbers.

The current race is especially charged given its political implications. Flávio, 45, a senator and lawyer representing the Liberal Party, entered the race as the clear successor to his father Jair Bolsonaro, who is currently serving a prison sentence after being convicted of attempting a coup following his 2022 loss. Facing him is Lula, who returned to power in those same elections and now watches as the national-conservative camp challenges his rule with considerable force.
The campaign in Brazil unfolded amid deep polarization, crime and economic problems, and extensive focus on foreign policy and relations with the United States. Bolsonaro centered much of his pitch on a strong alliance with President Donald Trump and presented his international ties as an advantage, while Lula attacked Washington and accused it of foreign interference in the country’s sovereignty—amid reports from Brazilian intelligence about suspected foreign meddling.

Now the slate resets ahead of the second round on October 25. Since Brazilian election law requires an absolute majority—more than 50% of valid votes to win in the first round—the votes cast for smaller candidates who were eliminated now become the central target. Both camps have just three weeks to try to absorb those floating votes and mobilize additional supporters. The central question remains wide open: Will Flavio manage to hold his advantage and unseat Lula, or will the left pull off a last-minute comeback?
