Brazil's Lula-Bolsonaro showdown unfolds in Trump's shadow — with the Amazon at stake

Brazil prepares for a presidential election on Sunday that could redefine its ties with President Trump, potentially see the Bolsonaro faction regain power, and impact the future of the Amazon. The intense competition between President Luiz Inácio Lula da Silva and Senator Flávio Bolsonaro has evolved into a broader struggle over U.S. influence in Latin America's largest country, with global climate ramifications at stake.

Trump recently signaled his close interest in Brazil's election, describing it as "very important," although he refrained from endorsing a specific candidate. The U.S. has inserted itself into the race through tariffs on Brazilian goods, which Lula has denounced as interference. This tension escalated in 2025 when the Trump administration targeted Brazilian Supreme Court Justice Alexandre de Moraes, leading to sanctions that were later lifted.

As Jair Bolsonaro, son of Trump ally and former President Jair Bolsonaro, is barred from running, Flávio Bolsonaro has vowed to carry on his father's political legacy. He faces Lula, who is seeking a fourth nonconsecutive term, in a runoff if no candidate secures over 50% of valid votes. Both candidates have distinct platforms: Lula emphasizes economic and social policies, while Flávio Bolsonaro champions conservative values, tax reductions, and stricter crime measures.

The election is crucial not only for Brazil's domestic affairs but also for the Amazon rainforest, which spans nearly 60% of the country. Deforestation rates have dropped since Lula's return to power, but Flávio Bolsonaro has advocated for relaxing environmental regulations and has expressed skepticism about climate change. Flávio Bolsonaro's meeting with Trump in May and his alignment with American initiatives like the "Shield of the Americas" further underscore the geopolitical stakes at play.
