Recent polls show Augusto Cury, Ronaldo Caiado, and Renan Santos clustered within a few points for the remaining top spots behind frontrunners Lula and Flávio Bolsonaro ahead of the October 4 first round. Cury has gained from a digital campaign and self-help author profile, while Caiado draws on his record as Goiás governor and PSD backing, and Renan Santos attracts younger anti-establishment voters through the Missão party. Late-campaign measures such as Bolsa Família expansions and ongoing debates have reinforced polarization around the two leaders, leaving limited room for shifts among the smaller contenders. A late surge by any one of these three or unexpected turnout patterns could determine fourth place.
