Datafolha will release a final pre-election poll for São Paulo governor on October 3, measuring the impact of the Globo debate between Tarcísio de Freitas and Fernando Haddad. The poll, registered September 27, will interview 2,520 voters. This is a routine pre-election survey, but it may signal momentum shifts in a tight race.
