Final Push: Lula and Bolsonaro Make Their Closing Arguments in High-Stakes Brazilian Election

President Luiz Inacio Lula da Silva and right-wing Senator Flavio Bolsonaro have officially wrapped up their intensive election campaigns, expressing strong confidence in securing a victory ahead of Sunday’s crucial first-round presidential vote.

Lula, 80, concluded his re-election bid on Saturday with a massive march through Sao Paulo, Brazil’s economic powerhouse, which his campaign highlighted as a record-breaking crowd for a closing event. Addressing his supporters, he declared that they would win the election in the first round, framing the choice as one between democracy and barbarism while vowing to defeat the far right. He also positioned the vote as a test of national sovereignty, issuing warnings regarding foreign meddling by Washington.

Meanwhile, Flavio Bolsonaro led a motorcycle caravan across towns in Sao Paulo state, replicating the signature campaign style of his father, before holding a final rally in Rio de Janeiro. The 45-year-old candidate, who is the son of former President Jair Bolsonaro and a known ally of Donald Trump, stated his absolute conviction that conditions are set for a first-round win. The former leader, 71, is currently serving a 27-year prison sentence following his attempt to overturn the 2022 election loss to Lula. During the rally, the younger Bolsonaro prominently displayed a portrait of his father.

While US President Donald Trump has not formally endorsed Flavio Bolsonaro, his remark that he is watching the race very closely has sparked considerable debate. Lula supporters view this interest as Washington attempting to interfere in the electoral process, whereas some Bolsonaro supporters battling cost-of-living challenges indicate they would welcome external pressure to spark domestic change.

Recent polling data released on Saturday indicates that Lula maintains an advantage, though his margin is shrinking, leaving open the possibility that neither candidate will secure an outright majority on Sunday. Such an outcome would push the contest into an October 25 run-off between the two leading candidates, which polls indicate would remain exceptionally competitive. This race proves significantly tighter than Lula's previous triumph in 2022, when he defeated the elder Bolsonaro by a margin of under two percentage points.

In addition to the presidential contest, the Bolsonaro campaign has faced mounting scrutiny surrounding a film-funding controversy. Flavio Bolsonaro is currently under investigation regarding the financing of Dark Horse, a biographical film about his father that received backing from an imprisoned banker linked to a major Brazilian financial scandal. Furthermore, Brazil’s Supreme Court permitted federal police in April to investigate potential defamatory statements made by Flavio Bolsonaro against Lula.

Bolsonaro has committed to pushing for his father's release from prison if elected and has repeated his father's unverified allegations questioning the accuracy of Brazil’s electronic voting system. Analysts note this rhetoric could establish the foundation to challenge the official results in the event of a defeat. Beyond the presidency, roughly 160 million registered voters across Brazil will also cast ballots on Sunday to elect lawmakers, governors, and senators, as right-wing candidates continue to build momentum across Latin America.
