Brazil's presidential frontrunner Luiz Inacio Lula da Silva slightly boosted his lead over incumbent President Jair Bolsonaro to 14 percentage points in a poll published on Thursday by pollster Datafolha, less than two weeks before the Oct. 2 first-round vote.
The Datafolha survey showed Lula with 47% voter support versus 33% for Bolsonaro in the election's first round, compared with 45% and 33%, respectively, in the previous poll.
