PSDB backs Otaviano Pivetta for Mato Grosso Governor, Mauro Mendes for Senator
The Brazilian Social Democracy Party (PSDB) has officially announced its support for Otaviano Pivetta's gubernatorial candidacy in Mato Grosso and Mauro Mendes's senatorial bid. This decision was formalized during the party's convention held on Tuesday, August 28th, at its headquarters in Cuiabá. The selection for the vice-governor position has not yet been determined. Otaviano Olavo Pivetta, an agricultural producer originally from Caiçara, Rio Grande do Sul, moved to Mato Grosso in 1982. He previously served as the vice-governor to Mauro Mendes, having joined the Republicanos party in 2022 to run on the same ticket for re-election, securing 68% of the valid votes. Pivetta assumed the role of state governor in March of the current year after Mauro Mendes declared his candidacy for the Senate. The convention also approved candidates for State and Federal Deputy positions, with lists provided for both. The deadline for party conventions to select candidates is August 5th, followed by registration with the Superior Electoral Court (TSE) by August 15th, with the official campaign commencing the next day. Brazilians will vote for president, governor, senators (two per state), federal deputies, and state deputies on October 4th. Pivetta's political career in Mato Grosso began in Lucas do Rio Verde, where he served three terms as mayor from 1997 to 2016, leaving office with over 80% public approval. He also served as a state deputy before being elected vice-governor in 2018. He assumed the governorship in March 2026.
This political alignment signifies a strategic consolidation of forces within Mato Grosso's electoral landscape. The PSDB's endorsement of Pivetta and Mendes suggests a shared vision for regional governance and a calculated effort to leverage existing political capital. As the election cycle progresses, the focus will likely shift to how this coalition addresses key regional development issues, such as agricultural policy and infrastructure, and whether their proposed solutions resonate with the electorate. The interplay between established political parties and evolving voter priorities will be crucial in determining the outcome, highlighting the dynamic nature of electoral politics in response to socio-economic conditions and governance expectations.
