Recent polling ahead of Brazil’s October 4 first round shows President Lula and Senator Flávio Bolsonaro as the clear frontrunners, with Lula typically at 38–46% and Flávio at 33–45% while other candidates such as Ronaldo Caiado, Romeu Zema, Renan Santos, and Augusto Cury remain in single digits or low double digits. This distribution points to a likely runoff between the two leaders, as no candidate appears positioned to secure an outright majority. Campaign activity intensified in August with the start of free electoral broadcasts and debates, while earlier scandals tied to Flávio’s financing efforts contributed to fluctuating margins that have since narrowed in several surveys. Voter fragmentation on the right and Lula’s incumbency advantage continue to shape expectations for which two names will advance.
