Mauro Mendes (União Brasil), the former Mato Grosso governor, holds the strongest position in the race for first place in the state's October 4, 2026, Senate election, consistent with recent polling showing him at 45-55% in consolidated first- and second-choice scenarios. Multiple surveys through early September, including from Paraná Pesquisas and Real Time Big Data, place him well ahead of Janaina Riva (MDB) and a field that includes José Medeiros (PL), Pedro Taques (PSB), and Carlos Fávaro (PSD), amid 25-51% undecided or blank responses. His sustained lead stems from high name recognition and prior statewide executive experience, while the two-seat structure allows voters to split preferences. No major late shifts have altered the ordering in the most recent data releases.
