Lula wins fourth term as Bolsonaro contests

Luiz Inácio Lula da Silva won Brazil’s presidential runoff on Sunday, securing a fourth non-consecutive term in office. The incumbent took more than 64 million votes against just under 60 million for Senator Flávio Bolsonaro. This margin represents a 4 percent difference in a contest that saw record-breaking late turnout. Lula is scheduled to take office on January 5, 2027.

The result followed a chaotic extension of voting hours requested by both candidates. A Supreme Court justice approved the measure minutes before the standard 5 p.m. close. This last-minute change disrupted the rapid tallying process that has characterized Brazilian elections since the 1990s adoption of electronic voting machines. The extension allowed an additional 14.1 million voters to participate in the second round. Analysts estimate that three-quarters of these new ballots went to Lula.

Senator Flávio Bolsonaro immediately challenged the outcome. He announced plans to request an annulment of the election, citing the irregular voting extension. His father, former President Jair Bolsonaro, is currently serving a 27-year sentence for a coup attempt. Flávio Bolsonaro visited his father, who is under house arrest, on Monday. Trump, who aligned with the Bolsonaro camp, suggested on Monday that the process was rigged. He told reporters that the tabulation looked bad and that the election had a rigged appearance, though he provided no specific evidence for the claim.

Lula’s digital strategy proved decisive in mobilizing previously uncommitted voters. Lawmaker André Janones led the effort through a WhatsApp channel called Lula's Army, which gathered nearly 11 million members. This aggressive social media operation pressured Meta to address alleged bias on its platforms. Brazil’s top electoral court ruled on October 15 that Meta must ensure equal treatment of both candidates. The campaign also mobilized former non-voters and supporters of third-party candidates, particularly in lower-income municipalities.

Kassio Nunes, president of Brazil’s electoral authority, recognized Lula’s victory on Sunday. Nunes was appointed to the Supreme Court by Jair Bolsonaro. Brian Winter, a Brazil analyst, noted that Brazilian power brokers are closing ranks behind Lula to avoid a truly contested election. Benjamin Gedan, director of the Stimson Center Latin America program, observed that while false fraud claims are dangerous, Lula’s clear margin and quick international recognition make an annulment difficult. Lula faces a right-wing Congress where Bolsonaro’s party holds the most seats.

The victory marks the first time since 1989 that a candidate recovered from a first-round deficit to win the runoff. Lula’s gains were strongest in wealthier metropolitan centers and his traditional base in the northeast. Flávio Bolsonaro remains a senator until January, when his term expires. The legal challenge sets the stage for a potential showdown between Brazil’s two polarizing political forces.
