Bolsonaro Surges Past Lula in Brazil's First Round, Setting Up Run-Off Showdown

Brazil's presidential election has been thrown wide open after right-wing Senator Flavio Bolsonaro defied opinion polls to finish ahead of incumbent President Luiz Inacio Lula da Silva in Sunday's first round, forcing a run-off vote later this month.

According to official results, the 45-year-old Bolsonaro captured 47 percent of the vote, while the 80-year-old Lula, who is seeking an unprecedented fourth nonconsecutive term, took 45.1 percent. Because neither candidate crossed the 50 percent threshold required to win outright, the two will meet again on October 25.

The outcome contradicted a series of pre-election surveys that had shown Lula leading by roughly three percentage points. Instead, the incumbent finished slightly behind, a result that has energised the Bolsonaro campaign and unsettled the governing Workers' Party, known as the PT.

Speaking to reporters in the capital, Brasilia, on Sunday, Bolsonaro welcomed the result and framed it as a decisive break with the current administration. He declared that voters had signalled a desire for change and saluted what he described as the end of the PT era. The senator, son of former President Jair Bolsonaro, now stands on the verge of leading Latin America's largest economy.

The first-round reversal leaves Lula in a difficult position, according to analysts. Oliver Stuenkel, a professor of international relations at the Getulio Vargas Foundation in Sao Paulo, noted that the incumbent must now contend not only with trailing after the first round but also with the arithmetic of the run-off. The ten other candidates who collectively won nearly eight percent of the vote are largely centre-right, making their supporters unlikely to swing behind Lula. Stuenkel added that Lula must overhaul his campaign strategy and, crucially, mobilise the roughly 30 million Brazilians, or 21 percent of the electorate, who abstained in the first round.

Al Jazeera's Monica Yanakiew, reporting from Rio de Janeiro, said Lula's backers believe their candidate failed to use social media as effectively as the right-wing camp, a shortfall they will need to address in the coming weeks. Yet historical patterns suggest such adjustments may prove insufficient. Stuenkel pointed out that no candidate who finished second in a first round has gone on to win the Brazilian presidency since 1989, barring something highly unusual in the next three weeks. He concluded that Flavio Bolsonaro is set to win.

The first round also delivered gains for the broader Bolsonaro family, reinforcing its grip on the Brazilian right. Michelle Bolsonaro, wife of the imprisoned former president and stepmother to Flavio, secured a Senate seat in the Federal District, which includes Brasilia. The 44-year-old had never held public office and only months earlier was embroiled in a public spat with her stepson, whom she accused of disrespecting her in social media videos. The two later reconciled.

Carlos Bolsonaro, the former president's second son, was elected to the Senate as the second most-voted senatorial candidate in the southern state of Santa Catarina. The youngest son, Jair Renan Bolsonaro, won a seat in the lower house of Congress. Experts attribute part of the family's political ascendancy to "antipetismo," a deep-seated hostility toward Lula's PT movement. In the concurrent congressional elections, Bolsonaro's Liberal Party secured 121 of the 513 seats in the Chamber of Deputies, while Lula's PT took 70.

The contest carries substantial regional and geopolitical weight. Al Jazeera's Lucia Newman, reporting from Sao Paulo, said Lula has been on a collision course with United States President Donald Trump, an ardent supporter of the Bolsonaro camp. That dynamic places Brazil at the centre of a fierce rivalry between Washington and Beijing for political, diplomatic and economic influence, particularly given Brazil's weight on all three fronts. While Bolsonarism is closely aligned with the United States and Israel, Brazil also maintains deep economic ties with China, its largest trading partner. Bolsonaro has cast Trump as an ally and is expected to deepen ties with Washington if elected.

A Bolsonaro victory would also revive the fate of his imprisoned father. The younger Bolsonaro has pledged to pursue a congressional amnesty for Jair Bolsonaro, who is serving a 27-year sentence for plotting a coup after losing the 2022 election to Lula by 1.8 percentage points. Such a move would require approval from both houses of Congress, which are currently dominated by conservatives.

The family's approach echoes that of Trump in the United States. Like the former American president, the Bolsonaros have promoted claims of rigged elections, and the insurrection that shook Brasilia in January 2023 bore similarities to the storming of the US Capitol two years earlier. Flavio Bolsonaro has also vowed to release his father's supporters who were jailed over the coup attempt.

Concerns about foreign interference have shadowed the campaign as well. Lula has accused the Trump administration of using tariffs and other measures to meddle in Brazilian domestic affairs, adding another layer of tension to a race already defined by polarisation. Vinicius de Carvalho, a lecturer in Brazilian studies at King's College London, emphasised that Latin America has been swept by a right-wing wave, with the election of governments aligned with the United States, a trend that now appears poised to reach Brazil.
