Lula Wins Brazil Presidential Run-off After First-Round Deficit

President Luiz Inácio Lula da Silva was declared the winner of Brazil’s presidential run-off on Sunday, obtaining 51.79% of valid votes (64.26 million) against Senator Flávio Bolsonaro’s 48.21% (59.83 million). Voter turnout rose to 80.8%, up from 78.9% in the first round, narrowing the gap that had seen Bolsonaro ahead by about 2.2 million votes in October.

Bolsonaro refused to concede and called for the result to be annulled after the Supreme Court extended voting by two hours, a request both campaigns had made due to transport disruptions and severe weather. Legal analysts said the challenge was unlikely to succeed, noting that Bolsonaro’s own campaign had sought the extension.

Analysts attributed Lula’s turnaround to a revitalised grassroots effort, increased youth mobilisation and a shift toward digital campaigning after a comparatively subdued first-round strategy. "It was this army that went to the streets, millions of people across Brazil, and young people just mobilised themselves," said Al Jazeera correspondent Monica Yanakiew.

Experts also pointed to Bolsonaro’s perceived overconfidence following his first-round lead, including premature appointments of ministers, which may have alienated voters. "If there is something Brazilian people don’t like, it’s arrogance," said economics professor Vinicius G. Rodrigues Vieira.

Higher participation in the second round contributed to the outcome; an estimated 33 million voters who abstained initially turned out for the run-off, according to international relations professor Fernando Brancoli.

Despite the win, Lula faces a Congress dominated by the Liberal Party and its allies, which control a majority in both chambers and could limit his legislative agenda. Economic challenges remain, with public debt above 82% of GDP and projected growth of 2.3% for next year. Security concerns and household debt were also highlighted as issues that shaped the election.

"No one is required to like the president-elect, but he must govern for everyone," Lula told supporters at a victory parade in São Paulo.

Lula, who will turn 81 in early June, will need to navigate these political and economic constraints as he begins his fourth term.
