Simone Tebet's Senate Bid Sparks Coalition Conflict Ahead of São Paulo Elections

Simone Tebet's Senate candidacy in São Paulo intensifies coalition tensions as PSB and PT vie for influence amid a heated gubernatorial race between Tarcísio de Freitas and Fernando Haddad.

    Key details

  • • Simone Tebet's Senate bid creates conflict within Lula's coalition in São Paulo.
  • • PSB favors Márcio França but aims to field both Tebet and França for Senate seats.
  • • Polls show a tight Senate race among Tebet, Marina Silva, and others.
  • • Tarcísio de Freitas leads Fernando Haddad in the São Paulo gubernatorial race, with both candidates preparing intense campaigns.

The 2026 São Paulo political landscape is heating up with Simone Tebet's recent entry into the Senate race, creating tensions within President Luiz Inácio Lula da Silva's coalition. Tebet, previously a minister, is negotiating to join the PSB, but faces resistance from the party's São Paulo faction which favors Márcio França due to his established political base. The PSB aims to secure both Senate seats in the state, but this ambition could clash with the PT, which is considering nominating Environment Minister Marina Silva from Rede.

Tebet's candidacy, reportedly encouraged by Lula and supported by Vice President Geraldo Alckmin, is yet to be formalized because of ongoing internal party conflicts. National PSB leaders anticipate her eventual affiliation, with a meeting between Tebet and Lula scheduled to finalize her candidacy. Márcio França has publicly endorsed Tebet as an "excellent candidate" but acknowledged Lula's decisive role.

Meanwhile, talks are underway about offering França the vice-presidential slot alongside Minister of Finance Fernando Haddad for the gubernatorial race, but this proposition has low enthusiasm within the party. Polling paints a competitive picture for the Senate, with Tebet, Marina Silva, and Federal Deputy Guilherme Derrite (PP) statistically tied according to Real Time Big Data surveys. Datafolha shows Haddad leading in the gubernatorial race at 30%, followed by Tebet at 25%, França at 20%, and Marina at 18%.

The gubernatorial race between current Governor Tarcísio de Freitas (Republicanos) and Haddad is shaping up to be more intense than in 2022. Both candidates plan to critique each other's governance records: Haddad has criticized Tarcísio's tax policies, including a contentious 20% ICMS tax on international purchases, while Tarcísio denies media bias and argues against Haddad's frequent tax hikes. Datafolha polls indicate Tarcísio leads with 44% voter intention against Haddad's 31%, signaling a complex and fiercely competitive campaign.

With intra-coalition negotiations ongoing, the Senate contest in São Paulo is a key battleground, reflecting broader political strategies ahead of the 2026 elections and underscoring the shifting alliances and rivalries shaping Brazil's most populous state.
