SAO PAULO (Reuters) -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.
In an expected second-round run-off, Lula would garner the support of 54% of voters versus 38% for Bolsonaro, a 16 point advantage, according to the poll, the same result from a week ago.
Bolsonaro's approval rating edged up to 32%, compared to 30% one week ago; and still above the 22% he held in December, after which his popularity ticked up thanks to welfare programs and measures to tackle inflation.
His disapproval came in at 44%, according to the poll, the same result from one week ago but down from the 53% seen in December.
Datafolha conducted 6,754 in-person interviews between Sept. 20-22. The poll has a margin of error of 2 percentage points up or down.
