SAO PAULO, Sept 17 (Reuters) - Brazil's President Luiz Inacio Lula da Silva maintained the numerical lead over Senator Flavio Bolsonaro in a potential runoff of the October election, a Datafolha poll showed on Thursday.
Lula is seen with 46% of the vote in a potential runoff, against 44% for the senator, a son of former President Jair Bolsonaro, according to Datafolha. The figures did not change from the previous poll last week.
Datafolha surveyed 2,002 people. Since the poll has a margin of error of two percentage points, both candidates remained statistically tied.
