Brazilian politician, Lula, and right-wing challenger, Flavio Bolsonaro, are neck and neck in the presidential runoff, with 47.8% of the vote in a second round, compared to 47.5% for the leftist candidate. The poll surveyed 5,008 people and has a 1-2,000-9% margin of error. The election has been closely watched since former President Jair Bolsenaro endorsed his son in December.
