SAO PAULO, Sept 11 (Reuters) - Brazilian 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 Friday.
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. The poll has a margin of error of two percentage points.
