Recent polling from institutes such as Real Time Big Data and Paraná Pesquisas shows ex-governor Mauro Mendes (União Brasil) consistently leading consolidated first-and-second vote intentions at 27-52%, followed closely by state deputy Janaina Riva (MDB) at 26-34%. This pattern positions Riva as the strongest contender for the second Senate seat in the October 4 election, where the top two candidates win eight-year terms. Mid-tier candidates including current senator Carlos Fávaro (PSD), federal deputy Zé Medeiros (PL), and ex-governor Pedro Taques (PSB) trail in the 13-18% range across surveys, while lower-polling names register minimal support. Trader pricing for second place aligns with these repeated survey results, reflecting the stable frontrunner dynamic in the race for Mato Grosso’s two vacancies.
