Brazil held a presidential election on Sunday, October 4, with nearly 159 million eligible voters choosing between incumbent Luiz Inácio Lula da Silva and Senator Flávio Bolsonaro, son of jailed former President Jair Bolsonaro. The race reflects a broader rightward shift across Latin America aligned with the Trump administration, while Brazilian labor unions and officials have publicly warned against U.S. interference in the vote.
Lula faces Trump-backed challenger in tight race
Lula, 80, is running for his seventh presidential election and serving his third term since 2023. Bolsonaro, 45, is a Trump ally and son of the former president serving a 27-year sentence for a coup attempt. If no candidate wins more than 50% of votes in the first round, the top two advance to a runoff scheduled for October 25. Brazil’s nearly 159 million eligible voters also elected 27 state governors, all 513 federal lower house members, and 54 of 81 senators on Sunday.
U.S. tariffs and diplomatic tensions dominate campaign
The Trump administration imposed high tariffs on Brazilian exports, later reduced from 50% to 25%, and revoked visas for unnamed officials. The U.S. Embassy and consulates suspended services starting October 2 citing security concerns. Brazilian labor unions issued a joint statement calling the consular suspension unnecessary and excessive, declaring Brazil a sovereign nation that will not accept foreign interference.
Bolsonaro’s ties to Trump administration draw scrutiny
In May 2026, Flávio Bolsonaro and his brother Eduardo visited the White House with Paulo Figueiredo and requested that the U.S. classify the PCC and Comando Vermelho as foreign terrorist organizations. Two days after the visit, U.S. Secretary of State Marco Rubio approved the designations. French magazine L’Express described the Bolsonaro family as Trump’s ideal vehicle for expanding U.S. influence in Brazil and Latin America, with Eduardo serving as the family’s chief liaison in Washington.
Right-wing momentum spreads across Latin America
Trump allies have won recent elections in Argentina, Colombia, Honduras, and Peru, part of what Trump calls the Donroe Doctrine, an updated version of the 19th-century Monroe Doctrine aimed at restoring U.S. pre-eminence in the Western Hemisphere. Lula has portrayed Bolsonaro as a stand-in for this broader right-wing movement and warned against foreign interference, which has given the incumbent a campaign boost despite his approval ratings falling during his third term.
Final Thoughts
Brazil’s October 4 vote reflects a regional shift rightward, with Lula defending against Trump-backed alternatives. If no candidate clears 50%, a runoff on October 25 will determine whether Latin America’s largest economy stays left or swings right.
