Former ministers Marina Silva (Rede) and Simone Tebet (PSB) are leading the race for Senate seats in the state of São Paulo [1].
The surge of these two candidates signals a potential shift in the political landscape of Brazil's economic hub as the election cycle progresses.
Two separate opinion polls conducted in May 2026 highlight the candidates' strength. A Datafolha poll released Monday, May 6, 2026, showed voter intention at 18% for Silva and 16% for Tebet [1].
Another poll by Paraná Pesquisas, released Thursday, May 21, 2026, showed an even tighter race [2]. In that survey, both Silva and Tebet tied for the lead with 36.6% of voter intention each [3].
The discrepancy between the two polls reflects a volatile electoral environment. While the Datafolha data suggests a narrower lead over other candidates, the Paraná Pesquisas figures indicate a much stronger consolidation of support for both women [1, 3].
Other reports have presented conflicting data regarding the front-runners. Some analysis of the Datafolha results suggested that Fernando Haddad and Geraldo Alckmin were leading the race instead [2].
Despite these contradictions, both Silva and Tebet remain central figures in the competition for the Senate in São Paulo [1, 2].
“Marina Silva (Rede) and Simone Tebet (PSB) are leading the race for Senate seats in the state of São Paulo.”
The competing poll results suggest a highly fragmented electorate in São Paulo. The significant gap between the Datafolha and Paraná Pesquisas numbers, ranging from 16% to over 36% for the lead candidates, indicates that voter sentiment is shifting rapidly or that polling methodologies are capturing different segments of the population. The prominence of two former ministers suggests a preference for candidates with established executive experience.
