Incumbent President Luiz Inácio Lula da Silva and Senator Flávio Bolsonaro remain the clear frontrunners to advance from Brazil’s October 4 first-round presidential vote under the two-round system. Recent national surveys show Lula at 38-40 percent and Flávio Bolsonaro at 34-37 percent, well ahead of Ronaldo Caiado and Romeu Zema, who each hover around 5 percent. Flávio’s position has been strengthened by his father Jair Bolsonaro’s December endorsement and the consolidation of right-wing support in a fragmented field, while Lula’s campaign relies on his incumbency and regional strongholds despite approval ratings in the mid-40s. No major new developments have shifted this dynamic in the past month, leaving the market focused on whether any late surge by secondary candidates or major endorsements could alter the top-two outcome before October.
