Professora Dorinha (União) and Vicentinho Júnior (PSDB) advanced from the October 4 first round to the October 25 runoff for Tocantins governor after finishing with 45.5% and 43.9% of valid votes respectively, a margin of roughly 1.6 points. The remaining candidates, including Laurez Moreira (PSD) at about 8%, were eliminated and their supporters now represent key swing blocs in coalition negotiations. Pre-election surveys had consistently shown the two frontrunners within a few points of each other in both first- and second-round scenarios, underscoring limited separation in voter preferences. Post-first-round statements from both camps emphasize outreach to undecided voters and regional bases ahead of the final contest, with trader pricing reflecting the narrow, unresolved dynamics of the runoff.
