Brazil's Presidential Runoff: Lula's Leftist Legacy Faces Bolsonaro's Resurgent Right-Wing Movement

Brazilians are heading to the polls again to decide between two candidates offering starkly contrasting visions for the nation, amidst rising concerns about crime, corruption, and a discernible rightward political shift across Latin America. Luiz Inácio Lula da Silva, the 80-year-old leftist President, was initially favored to win a fourth term, aiming to cap a political career that has significantly influenced Brazil for over two decades. However, his path to victory has become more challenging, finding himself in a runoff against Flávio Bolsonaro, the eldest son of former President Jair Bolsonaro. Bolsonaro's surprisingly strong first-round performance defied expectations, positioning the younger candidate as a formidable contender against one of Latin America's most prominent left-wing figures.

The election pits the octogenarian Lula's bid for another term against the 45-year-old Bolsonaro's effort to build on his first-round momentum and secure a final victory. The outcome is expected to have significant implications beyond Brazil's borders. As right-wing governments increasingly gain traction throughout Latin America, this runoff could determine whether Brazil, the region's largest economy, aligns with a more conservative bloc, potentially mirroring the influence of the Trump administration if Flávio Bolsonaro achieves what his father could not in 2022: defeating Lula.

A First-Round Upset

According to Brazil’s Superior Electoral Court, Bolsonaro garnered 2.2 million more votes than Lula in the initial round. With neither candidate securing the necessary majority to win outright, both campaigns are now focused on appealing to a dwindling number of undecided voters and energizing their bases in a country deeply divided by its political future. This first-round result highlighted vulnerabilities in Lula's reelection campaign, stemming from public frustration over the cost of living and crime, as well as challenges in mobilizing his traditional supporters. It also underscored the enduring strength of Jair Bolsonaro's movement, even as the former president is currently serving a prison sentence for attempting to overturn his 2022 election loss.

Crime, the Economy, and Shifting Strategies

Public safety has emerged as a central theme in the campaign. A September Quaest/Pax survey indicated that 28 percent of Brazilians identified violence as the nation's most pressing issue, followed by corruption (22 percent) and the economy (19 percent). Brian Winter, editor-in-chief of Americas Quarterly, noted that this focus strongly favors the Bolsonaros, who have consistently championed a tough stance on crime. Flávio Bolsonaro has pledged to classify major criminal organizations as terrorist groups, increase prison capacity, and lower the age of criminal responsibility. He stated on October 13, "Those who think I’m radical on public security haven’t seen anything yet," even suggesting that El Salvador's stringent approach under President Nayib Bukele was insufficient.

Lula has faced difficulties reconciling his party's traditional platform with calls for more aggressive crime-fighting measures. A widely shared video clip from last year, where Lula suggested that drug traffickers could also be victims of drug users, reinforced what Winter described as a "longstanding perception that the Brazilian left is soft on crime." Lula later admitted to having expressed himself poorly.

During a televised debate on Sunday, Bolsonaro questioned Lula about temporary prison leaves. Lula defended rehabilitation programs but stated that serious offenders should not be eligible, subsequently inquiring if Bolsonaro would pardon his father. Flávio Bolsonaro did not directly address this question but has repeatedly expressed a desire for Jair Bolsonaro to be present at his inauguration. This exchange followed a notable shift in the runoff campaign: in an effort to attract broader voter support, Lula signaled his openness to lowering the age of criminal responsibility from 18 to 16 for certain serious offenses, though he opposed its inclusion in a pending constitutional amendment. Winter characterized this move as "as close to anathema as you can get in his workers’ party," which has historically opposed such changes. He added, "Lula is now yielding in the campaign’s final days because he recognizes that this may be his biggest vulnerability," illustrating the extent to which Lula is willing to moderate his stance to appeal to more conservative voters, despite his past resistance to such measures.

Lula has also faced criticism regarding the economy and affordability. During his previous terms, a commodities boom facilitated the uplift of millions of Brazilians from poverty into the middle class. This time, many voters report feeling a lack of progress. While Lula can point to low unemployment and easing inflation, these statistics have not significantly altered public perception among households struggling with daily expenses. Winter drew a parallel to the 2024 US presidential election, where positive economic indicators did not overcome voter frustration with prices under President Joe Biden and then-Vice President Kamala Harris.

"The headline numbers for the economy look good," Winter observed. "But everyday people keep saying that they don’t feel like the economy is prospering. They feel like their standard of living has declined." Despite these economic concerns, many voters remain loyal to Lula due to the social gains achieved during his earlier presidencies and fear that a Bolsonaro administration could reverse social rights. Flávio Bolsonaro has attempted to mitigate these fears by distancing himself from some traditionally conservative stances. On October 16, Congress approved a constitutional amendment to gradually reduce Brazil's standard six-day workweek to five days without pay cuts. Bolsonaro, who had previously opposed the proposal, reversed his position and voted in favor. "This is another case of the Bolsonaros being ideologically flexible enough to get elected," Winter commented. "Both sides are doing this in the race’s final days. It’s breathtaking."

Key Demographics: Women and Religion

Experts and campaigns agree that winning over women is crucial for both candidates. Women constitute nearly 53 percent of registered voters and have shown less support for Bolsonaro-aligned candidates compared to men. An October 15 Datafolha survey indicated Lula leading among women 49 percent to 40 percent, while Flávio led among men 52 percent to 40 percent. "Women are the key demographic," Winter stated. Malu Gatto, an associate professor of Latin American politics at University College London, noted that the gender gap widened after Jair Bolsonaro's emergence in 2018, with men increasingly leaning right and women showing greater support for the Workers’ Party. Both campaigns have also addressed violence against women, particularly femicide, following several high-profile cases that garnered national attention. Brazil reported 1,571 femicides in 2025, the highest number since the crime was legally defined in 2015, according to the Brazilian Forum on Public Safety.

Gatto explained that conservative approaches typically emphasize stricter penalties for aggressors, while the left prioritizes victim support, including shelters and specialized services. Flávio Bolsonaro's first televised advertisement prominently featured his wife and daughters, with him stating, "At home, they’re the ones in charge. And that’s a good thing" – a notable strategy for a movement historically stronger among men. Former first lady Michelle Bolsonaro, who was elected to the Senate, has also played a significant role in attracting women to the Liberal Party. Her public dispute with Flávio, though later resolved, highlighted the importance of this demographic to his campaign. "Michelle has her own electoral capital, among women and among evangelicals," Gatto observed. "She has legitimacy with women and evangelicals in a way Flávio doesn’t."

Evangelicals, a growing segment of the predominantly Catholic population, have become a vital voting bloc for the right. Datafolha found Bolsonaro leading among evangelicals 62 percent to 29 percent, while Lula held a lead among Catholics 52 percent to 42 percent.

Regional Dynamics and Turnout

Geographical factors also play a role. Approximately 40 percent of Brazil's electorate resides in the Southeast, where Flávio secured 51.4 percent of valid votes in the first round, compared to Lula's 39.7 percent. The right-wing senator won all four states in this region, including São Paulo, Minas Gerais, and Rio de Janeiro – Brazil's three largest electoral states. Minas Gerais has historically voted for the eventual winner in presidential elections since 1989. Lucas Fernandes, a political analyst at BMJ, described Minas Gerais as a microcosm of Brazil's political divisions due to its mix of industrialized cities and poorer rural areas. Lula narrowly defeated Jair Bolsonaro there in 2022; this time, Flávio won with 48.24 percent of valid votes against Lula's 43.33 percent, a margin of nearly 590,000 votes.

In the Northeast, Lula's traditional stronghold, his first-round margin of victory was smaller than in previous elections. His vote share in Maranhão decreased by almost five percentage points, marking the sharpest decline in the region and indicating challenges in mobilizing his core supporters. Beyond persuading voters, mobilizing those who abstained in the first round is critical. One in five eligible Brazilian voters did not vote, a significant group in a race decided by just 2.2 million votes. With 94 percent of voters indicating they had already made up their minds according to Datafolha, encouraging turnout could be as important as swaying the few remaining undecided voters.

Factors Behind the Shift

The first-round results prompted an important question for Lula's campaign and analysts: How did a president who defeated Jair Bolsonaro end up losing to his son, a candidate initially perceived as less politically formidable? "I think the most important takeaway is that today’s Brazil is turning right," Winter stated, adding that voters have become "more conservative over the last 10 to 15 years." This trend mirrors broader electoral shifts across Latin America, where several presidential elections since April 2025 have resulted in victories for right-wing or center-right candidates. A July Datafolha survey showed 44 percent of Brazilians identifying with right or center-right political values, compared to 39 percent on the left or center-left, reversing the 2022 balance.

Fernandes highlighted tactical voting – where voters choose a candidate with a better chance of winning or defeating a rival – as a potential explanation for the early October surprise. "All the alternative candidates, at least the competitive ones, were on the right," Fernandes explained. "So Flávio was much more likely than Lula to benefit from that shift in tactical voting, because he is ideologically much closer to the other candidates who were in the race." Another factor, Fernandes noted, is the strong rejection of Lula's Workers’ Party among Brazilians who, while not identifying with the Bolsonaro movement, are determined to prevent Lula's reelection. This sentiment appears stronger now than in 2022, when Lula benefited from widespread opposition to Jair Bolsonaro following a presidency marked by controversy over his government's pandemic response.

Fernandes also pointed to Lula's campaign underestimating the influence of social media, an area where the right has consistently focused its strategy. "The right understood this and applied it on several fronts, not just to Flávio’s candidacy, while the left failed to make that transition," Fernandes said. Winter agreed, emphasizing, "The most important venue for Brazilian politics today is WhatsApp," describing how family groups and private conversations, influenced by memes and short videos, can shape decisions in the final campaign days. This difference was reflected in campaign spending: paid social media was Flávio's second-largest expense in the first round, while it ranked sixth for Lula, according to financial disclosures filed with Brazil’s Superior Electoral Court.

Corruption Allegations and Political Fatigue

Part of the shift towards the right in Brazil is attributed to the association of the left with corruption, although scandals have affected both campaigns. During Sunday's debate, Lula challenged Bolsonaro to release his financial records and questioned his ties to Daniel Vorcaro, the former head of the collapsed Banco Master, whose alleged connections to influential figures have implicated Brazil's political and judicial establishment. Flávio, in turn, accused Lula of corruption and raised allegations concerning the president's eldest son, known as Lulinha. Lula's previous corruption convictions were annulled in 2021.

On Monday, Lula announced he would authorize the disclosure of his banking and telephone records, along with those of his five children, to Brazil's electoral court, proposing that Flávio Bolsonaro do the same for himself, his family, and his businesses. Flávio responded by stating he would accept the challenge if Lula also opened the banking and tax records of his former chief of staff and disclosed first lady Janja da Silva’s expenses and presidential corporate card spending. Experts suggest these corruption allegations are exacerbating political fatigue in Brazil. "It reinforces the disgust and apathy that Brazilians feel with their political system as a whole," Winter told CNN.

International Repercussions

US President Donald Trump has praised Flávio Bolsonaro's electoral performance without formally endorsing him, despite strained relations between the US and Lula's administration due to tariffs and pressure over Jair Bolsonaro's prosecution. Tensions were evident during Sunday's debate, where Lula accused the Bolsonaro family of aligning with US interests at Brazil's expense, while Flávio rejected the charge and criticized Lula's foreign policy. A Bolsonaro victory could align Latin America's largest economy more closely with the US, particularly on security and organized crime issues, and bolster the wave of conservative governments elected across the region. Lula, conversely, has prioritized multilateralism, ties with the Global South and China (Brazil's largest export market), and has opposed Trump's tariff measures as a defense of national sovereignty.

The next president will face a more conservative Congress. A close election result could also test the country's stability, particularly following Jair Bolsonaro's attempts to overturn his 2022 defeat, which led to the January 8, 2023, attacks on government institutions. Bolsonaro denies any wrongdoing. For Lula, a win would signify another significant political comeback. For Flávio Bolsonaro, it would mean the return of his father's movement to the presidency, despite Jair Bolsonaro's conviction and imprisonment.
