Flávio Bolsonaro, the 45-year-old son of jailed former president Jair Bolsonaro, won 47% of the first-round vote to Lula's 45.1%, forcing a 25 October runoff in which the younger Bolsonaro enters as strong favourite. With 56.1 million votes to Lula's 53.8 million and a congress stacked with allies, the result is less a horse race than a structural shift in Brazilian power. The scale of the far-right wave exceeded every major poll. Carlos Bolsonaro and Michelle Bolsonaro won senate seats; youngest son Jair Renan took a lower house seat; former infrastructure minister Tarcísio de Freitas was reelected governor of São Paulo. Of 54 senators elected, 34 came from the right or far right — a supermajority with direct implications for the supreme court, since only the senate can impeach justices. Bolsonaristas made this race a priority precisely because the court jailed the elder Bolsonaro for his coup attempt. The dynastic architecture is now explicit. Flávio Bolsonaro has said winning the presidency would allow him to free his father, who is serving a 27-year sentence for plotting a failed coup after losing the 2022 election to Lula. The family now controls or contests the presidency, the senate, the lower house, and the governorship of Brazil's economic engine. This is not a populist insurgency — it is an institutional takeover using democratic mechanics. Lula, 80, running for a historic fourth non-consecutive term, acknowledged the blow. "I confess to you that I was convinced I was going to win the election in the first round," he told supporters in São Paulo. His campaign will now pivot to a two-candidate contrast, hoping to surface Bolsonaro's documented links to Rio's criminal underworld, including the family's employment of close relatives of a notorious contract killer. The international dimension is not background noise. Donald Trump became a key election issue, with Lula accusing the US president of trying to swing the vote to "colonise" Brazil and appropriate its natural resources. Bolsonaro has promised closer ties with Trump, who sees a rightwing Brazilian victory as cementing US influence across Latin America after pro-Trump leaders won in Chile, Colombia, and Peru. Brazil is the capstone. Public frustration over cost of living and urban violence provided the fuel, but the Bolsonaro machine provided the infrastructure. The far-right's congressional sweep means that even if Lula somehow wins the runoff, he would face a legislature capable of paralysing his agenda or impeaching court justices who check executive power. The election is now about whether democratic institutions survive contact with a movement whose patriarch tried to overthrow them less than four years ago. Brazil's 159 million voters chose more than a president on Sunday. They chose state parliamentarians, 27 governors, 513 lower house members, and 54 senators. Across nearly every layer, the far right advanced. The second round is a formality the numbers favour Bolsonaro to win — the real question is what happens to institutional checks once a dynasty built on coup nostalgia holds the keys.
