As the 2026 Brazilian presidential election approaches, polling shows a highly competitive field. Early data indicates President Luiz Inácio Lula leads in first-round intentions, but faces technical ties with Flávio Bolsonaro and Ronaldo Caiado in various simulated second-round scenarios.

Campaign strategies have increasingly focused on specific demographics, particularly women voters. Flávio Bolsonaro has proposed judicial reforms involving the Supreme Federal Court (STF) and the creation of support centers for victims of violence. Meanwhile, President Lula has centered his platform on gender equality, economic independence, and the fight against feminicide.

Voter demographics remain split along gender and regional lines, with Lula maintaining strength among women and in the Northeast, while Bolsonaro performs better among men, evangelical populations, and in the South.

Recent polling from BTG Pactual/Nexus reinforces this polarized landscape. In a simulated first-round scenario, Lula holds 40% of voter intentions, followed by Flávio Bolsonaro at 35%. Other candidates include Ronaldo Caiado (5%), Renan Santos (4%), and Romeu Zema (3%).

In potential second-round runoffs, the margin between Lula and Flávio Bolsonaro is narrow, with Lula leading 47% to 44%—a result within the poll’s 2% margin of error. Lula also maintains advantages in simulated runoffs against Romeu Zema (47% to 40%) and Renan Santos (46% to 37%).

Geographic and religious divides persist. Lula shows stronger support in state capitals, leading Flávio Bolsonaro 55% to 35% in a second-round simulation, while the gap narrows in rural interior regions. Religious affiliation remains a major factor: Flávio Bolsonaro leads significantly among evangelical voters with 58% compared to Lula’s 32%, while Lula maintains higher support among Catholics and those with no religious affiliation.
