Flavio Bolsonaro's commanding 98% implied probability for first place in Mato Grosso during the October 25 second round stems from his decisive first-round performance there, where he captured 65% of valid votes against Lula's 29% on October 4. The Center-West agricultural state has consistently favored right-leaning candidates in recent cycles, and pre-election polls from firms like Quaest and AtlasIntel projected similar double-digit leads in runoff scenarios. Cross-party local endorsements and the elimination of other right-wing contenders have further consolidated support. A reversal would require unusually large swings in turnout or voter preferences over the next three weeks, though national campaign dynamics could still exert limited influence on the final margin.
