The latest poll shows Bolsonaro ahead of Lula in Brazil's second round

Despite polls showing the right-wing senator leading the left-leaning president, pundits are still challenging the race.

Another poll shows leftist Brazilian President Luiz Inacio Lula da Silva trailing right-wing senator Flavio Bolsonaro in the Oct. 25 runoff.

The poll, published by CNT/MDA on Friday, showed Bolsonaro with 46.8 percent of the vote, while Lula won 45.9 percent.

The end of the latest forecast comes a day after a Quaest poll showed Bolsonaro with 46 percent of the vote, compared to Lula's 44 percent. A separate Datafolha poll showed Bolsonaro with 47 percent of the vote to Lula's 45, down from 49 percent the previous week.

All three polls are currently within a 2 percentage point margin of error, meaning the race is still viewed as a toss-up by many pundits. Still, they underscore the uneasy political climate for Lula, who was predicted a month ago to easily win at the polls.

That was before Bolsonaro, the son of former president Jair Bolsonaro, won the most votes of any candidate in the first round of voting on Oct. 4.

Bolsonaro won 56,104,503 votes compared to Lula's 53,879,538.

This senator is close to the political personality of his father, who was banned from running for re-election until 2030 after the ruling of the Electoral Court. He abused his authority to cast doubt on the 2022 presidential election.

The elder Bolsonaro remains under house arrest while serving a 27-year sentence linked to an attempt to annul the 2022 vote, which he lost to Lula.

Flavio Bolsonaro, 42, has pledged to crack down on crime and drug-trafficking and cut off taxes that are used to pay for government programs. A victory would make him the latest conservative leader to ally with US President Donald Trump to seize power in the region.

Meanwhile, Lola holds regular rallies in hopes of energizing her fans. The 80-year-old politician is seeking a fourth non-consecutive term after nearly five decades of political activity.

On Wednesday, Congress passed an amendment that would give workers two days of paid vacation instead of one a week.

The move gives Lula a major victory on one of his most important social reform promises just days before the vote.

The election comes at an important time for Latin America's largest economy. Brazilians grapple with concerns about crime and the cost of living, while the country faces strained relations with the United States. Voting is also being watched closely across the region, which has shifted sharply to the right in a series of recent elections.
