Reinaldo Azambuja's extensive experience as former Mato Grosso do Sul governor and his broad name recognition have anchored trader consensus around his strong position for first place in the October 4 Senate vote. Both he and fellow PL candidate Capitão Contar benefit from their party's alliance and shared coligação, which consolidated center-right support after Nelsinho Trad stepped aside as Azambuja's suplente. Recent Quaest polling shows the pair leading the field with Contar edging ahead in some first-preference scenarios, yet Azambuja maintains consistent strength across combined-vote measures amid a fragmented field of ten candidates. Opposition votes remain split among Soraya Thronicke, Vander Loubet, and smaller contenders, limiting any single rival's path to topping the tally. With the first round days away, the market pricing reflects Azambuja's structural advantages in turnout and voter familiarity.
