The Mato Grosso Senate race for second place remains highly fragmented and closely contested ahead of the October 2026 vote, with polling averages showing multiple contenders clustered in the low-to-mid teens behind the top two names. Recent surveys from late July and early August highlight voter flexibility in selecting two senators, keeping probabilities tight among figures such as Fávaro, Pedro Taques, José Medeiros, and Janaína Riva as campaigns focus on agricultural policy priorities and state-level alliances. This dynamic reflects broad indecision in the consolidated second-preference vote, where no single candidate has consolidated a clear edge. Upcoming debates or shifts in party coalitions could alter positioning before ballots are cast.
