Brazilian President Luiz Inacio Lula da Silva's advantage over Senator Flavio Bolsonaro has narrowed ahead of the October election, according to a Datafolha poll released Thursday. Lula was backed by 46% of respondents in a potential runoff, compared with 44% for Flavio Bolsonaro, the son of former President Jair Bolsonaro. In a mid-August poll, Lula had 47% and Bolsonaro 43%, reducing the gap from four percentage points to two. The report was filed by Andre Romani and edited by Chris Reese.
