What We Know About Brazil's Lula-Bolsonaro Presidential Runoff

Brazilians voted Sunday in a presidential runoff between incumbent leftist president Luiz Inácio Lula da Silva, 80, and far-right senator Flávio Bolsonaro, 45, after neither candidate won a majority in the first round, according to The Guardian. The two candidates entered the vote virtually tied, the Guardian reported Sunday, after Bolsonaro's first-round lead narrowed over the three-week runoff campaign.

Who is running in Brazil's presidential runoff?

Lula da Silva, the sitting leftist president, is attempting what the Guardian on Sunday called an unprecedented comeback after finishing behind Bolsonaro in the first round. Flávio Bolsonaro is a senator and, per the Guardian, a congressman for more than 20 years who has passed few bills during that tenure. He is the eldest son of former president Jair Bolsonaro. Lula cast his ballot Sunday in São Bernardo do Campo, the industrial city where the Guardian noted his political career began nearly half a century ago. Flávio Bolsonaro voted at a school in Rio de Janeiro's north zone, telling reporters afterward, as quoted by the Guardian, "I think the time has come for real change. Brazil can't take another four years the way things are ... Everyone's life has got worse."

Why was the first round so close?

The Guardian reported that the gap between the two candidates in the first round was less than 2% of the vote, which it described as the narrowest margin ever recorded in a first-round Brazilian presidential contest. Bolsonaro's first-round victory came as a surprise, the Guardian noted, since he had not been leading most pre-election polls going into that vote. The win made him the runoff favorite three weeks ago, according to the outlet, but Lula's campaign gained ground in the weeks that followed, closing the race to a virtual tie by Sunday's vote, the Guardian reported.

What does Jair Bolsonaro's prison sentence have to do with the race?

Flávio Bolsonaro's father, former president Jair Bolsonaro, is under house arrest serving a 27-year sentence for attempting a coup to overturn his 2022 election loss to Lula, according to the Guardian. That history has shaped Lula's closing message: the Guardian reported that the president spent much of the runoff campaign stoking fears over what a return to power by a member of the Bolsonaro family could mean for the country.

How did turnout factor into the race?

Abstention in the first round reached a record high, the Guardian reported, and disproportionately affected Lula's voter base. That dynamic pushed Lula's runoff strategy toward turnout operations rather than persuasion alone, according to the outlet's reporting. The Guardian also described leftist demonstrations that swept the country during the runoff campaign in support of Lula, many of which it said emerged organically among young people. Lula, after voting Sunday, said he had "never seen anything like" that groundswell, telling reporters, as quoted by the Guardian, "What the people have done for me in these past few days is something I can never repay. It is so much generosity, so much affection, so much love."

What is the timeline of the runoff vote?

The Guardian's reporting, filed from Rio de Janeiro and first published at 4 a.m. Eastern time Sunday with an update at 10:41 a.m., frames three key moments. First, the initial round produced the less-than-2% margin that the outlet called the narrowest first-round result on record, with Bolsonaro emerging as the surprise front-runner despite trailing in most pre-vote polling. Second, over the three weeks that followed, Lula's campaign closed that gap, shifting the race from a Bolsonaro advantage to a tie by the morning of the runoff, according to the Guardian's account. Third, both candidates voted Sunday morning — Bolsonaro in Rio de Janeiro's north zone, Lula in São Bernardo do Campo — before the polls that will determine the outcome. The Guardian's dispatch, reported by Tiago Rogero, does not include final runoff results, reflecting the vote's status as still underway at the time of publication.

What happens next?

The Guardian's Sunday report does not specify a results timeline beyond describing the vote as "highly unpredictable," with the two candidates going into the contest virtually tied. Any outcome will test whether Lula's late-campaign turnout push among previously abstaining voters was enough to offset the record-narrow first-round deficit, or whether Flávio Bolsonaro converts his first-round momentum into a win that would return the Bolsonaro family name to Brazil's presidency while his father remains under house arrest.
