# Brazil 2026 election dynamics > Live situation record from CLSTR: https://clstr.news/situations/brazil-psdbcidadania-backs-acio-neves-2026 > Updated: 2026-08-02T11:22:42.000Z. Sources: 33. Developments: 11. The centrist federation around former PSDB president Aécio Neves continues to offer a third‑way alternative, backed by senior centrists Tasso Jereissati and Ciro Gomes, while PSDB leaders in Mato Grosso support Governor Otaviano Pivetta’s re‑election. Union Brasil (UB) remains in internal conflict, promoting Joelma Costalonga as a possible vice‑governor on Ricardo Ferraço’s ticket and facing a split over a late‑stage state convention, bribery accusations, and a gender‑based violence dispute involving Flávio Bolsonaro. Five of the eight largest Chamber parties have yet to endorse a presidential candidate, leaving the Bolsonaro‑Lula contest undecided. President Lula has signaled support for a women‑focused ticket in Goiás, meeting PT deputy Adriana Accorsi and PSB legislator Aava Santiago; PT confirmed Marília Campos’s Senate run in Minas Gerais and is weighing other governorship options. In August, parties formalised slates: MDB re‑nominated Governor Hana Ghassan in Pará; Republicanos presented a full slate in Mato Grosso do Sul, endorsing Vice‑Governor José Carlos Barbosa; PL allied with MDB to back Senate candidate Janaina Riva; PSOL‑Rede nominated Cíntia Dias for the Goiás Senate; Unidade Popular put forward Luciana Amorim for governor. Further conventions in early August added details: MDB in Pará confirmed Senate candidates Helder Barbalho and Chicão; Republicanos in Mato Grosso do Sul announced 25 state‑assembly and nine federal‑deputy candidates and backed Governor Eduardo Riedel and Vice‑Governor Barbosinha; Avante listed nine federal and 23 state‑deputy candidates in Campo Grande; PL launched a project supporting deputy Coronel David’s re‑election and a Senate ticket of José Medeiros with Janaina Riva; the Mato Grosso do Sul coalition also confirmed Senate candidates Reinaldo Azambuja and Capitão Contar. These events mark the opening of campaign activity across the federation. ## Claims - Hana Ghassan was officially nominated by the MDB for re‑election as governor of Pará.
