Eduardo Riedel holds a commanding lead in the Mato Grosso do Sul governor race due to his position as incumbent with strong recent polling and broad coalition support. A late August Quaest survey showed him at 40% in the first-round simulated vote, more than triple the next candidate, alongside 62% government approval and 66% of voters saying he merits re-election. His PP ticket secured endorsements from multiple parties, including a decision by PL not to field a rival candidate. The October 4 first-round vote, with a possible runoff on October 25, favors the sitting governor under current conditions, though shifts in undecided voters or unexpected events could narrow the gap before ballots close.
