A series of polls on Saturday (October 3, 2026) showed Brazilian President Luiz Inacio Lula da Silva slightly ahead of Senator Flavio Bolsonaro before Sunday’s first-round vote, and a close race in a likely runoff between the leftist incumbent and his right-wing challenger.
If no candidate wins more than 50% of valid votes — which exclude blank and null ballots — on Sunday (October 4, 2026), the two frontrunners advance to a second-round runoff on October 25.
