In a continuation of a recent trend favoring right-wing leaders across Latin America, Flavio Bolsonaro emerged as the front-runner in Brazil’s presidential election first round, solidifying his position ahead of a runoff against incumbent President Luiz Inacio Lula da Silva. Bolsonaro’s performance, capturing approximately 47 percent of the vote and finishing just ahead of Lula by two points, marks a significant moment in the region’s shifting political landscape.
Over the past 18 months, seven presidential elections in Latin America have been won by right-wing candidates, a development that aligns closely with the strategic objectives pursued by the Trump administration. Washington has sought to deepen its influence in the region through a combination of tariffs, sanctions, military interventions, and diplomatic pressure, framing these efforts largely around combating drug trafficking organizations. Central to this campaign has been the designation of 21 criminal groups in Latin America as terrorist entities, with the Pentagon carrying out numerous strikes targeting suspected traffickers—actions that have drawn scrutiny regarding their legality.
A key priority of the Trump administration has been the establishment of a multi-national coalition to counter drug cartels, known as the Shield of the Americas. Eighteen countries have joined this effort, with Colombia, Ecuador, Guatemala, and Honduras lending military cooperation to U.S. forces. Bolsonaro has expressed support for adding Brazil to this coalition, promising to collaborate on combating domestic gangs. While he initially indicated openness to U.S. military intervention in Brazil, he later tempered these claims, suggesting cooperation would focus primarily on intelligence sharing. Nonetheless, Bolsonaro successfully influenced the Trump administration’s decision to label two Brazilian criminal organizations as terrorist groups, enhancing the scope for joint operations and sanctions.
The current wave of regional political realignment is fueled by widespread dissatisfaction with incumbent governments, concerns over public security, and a resurgence of socially conservative values. In Brazil’s legislative races, right-wing candidates, including several from the Bolsonaro family, made notable gains in both the lower house and the Senate, further consolidating their political influence.
Despite these developments, experts remain cautious about the effectiveness of the U.S.-led anti-cartel initiatives. Critics point out that drug flow has not significantly diminished despite numerous military actions, and details on operational coordination among coalition members remain sparse. There are also ongoing debates about the implications for national sovereignty, given the asymmetry of power between the United States and individual Latin American countries. Bolsonaro has rejected claims that U.S. involvement threatens sovereignty, instead framing the drug cartels as the primary danger.
Bolsonaro’s policy approach to crime draws inspiration in part from El Salvador’s Nayib Bukele, whose aggressive security measures have lowered crime rates but also provoked concerns regarding human rights. The Brazilian presidential runoff is expected to be fiercely contested as both candidates seek to attract millions of voters who abstained from the first round—a record 33 million—despite compulsory voting laws.
A Bolsonaro victory would represent a significant geopolitical win for the Trump administration, potentially aligning Brazil more closely with U.S. regional objectives and displacing one of Trump’s most vocal critics in Lula. However, Bolsonaro’s campaign faces challenges, including ongoing corruption allegations and contentious proposals such as amnesty for his father and others involved in violent incidents. The outcome of the forthcoming runoff will be closely watched as Latin America’s political trajectory continues to evolve.
