**Mauro Mendes maintains a commanding lead in Mato Grosso’s Senate race for first place, backed by consistent polling advantages as the former governor seeking one of two federal seats.** Multiple September 2026 surveys, including Paraná Pesquisas and Real Time Big Data, place him well ahead in consolidated first- and second-choice intentions, often exceeding 45-55 percent while Janaína Riva trails in the low-to-mid 30s. Other contenders such as José Medeiros, Pedro Taques, and Carlos Fávaro register lower double-digit or single-digit support. High undecided rates persist across polls, yet Mendes’s name recognition from his governorship and recent campaign positioning have sustained trader consensus around his frontrunner status ahead of the October election. No major late shifts have altered this dynamic.
