Flavio Bolsonaro holds a commanding position in Tocantins for the October 25 second-round presidential runoff due to his first-round performance there, where he secured 50.44% of valid votes compared to incumbent Lula's 43.42%, reversing prior PT advantages in the state. Pre-election surveys consistently showed the PL senator leading or tied in head-to-head matchups, reflecting stronger regional support among right-leaning voters and alignment with national trends favoring his candidacy. Lula trails at low implied probability in trader consensus because barriers include limited time for momentum shifts before runoff voting. Potential challenges remain from differential turnout, last-minute campaign mobilization, or endorsements that could narrow the gap in this closely watched northern state.
