Vicentinho Júnior (PSDB) holds a clear lead in the Tocantins gubernatorial runoff market after advancing from the October 4 first round, where Professora Dorinha (União Brasil) narrowly led with 45.52% to his 43.94%. Recent Quaest polling for the October 25 second round shows Vicentinho ahead 49% to 42%, reversing the first-round order amid consolidated support from eliminated candidates and campaign momentum. Additional surveys, including Paraná Pesquisas, indicate similar or wider margins for the PSDB candidate. Traders appear to weigh these polling trends, the tight runoff structure, and scheduled events such as the October 22 debate as key drivers of the current pricing.
