Leftist former President Luiz Inacio Lula da Silva's lead has narrowed to 9 points from 14 in one month, but he would still win a second-round runoff soundly if Brazil's election were held today, according to a new poll published on Wednesday.
Lula is expected to challenge far-right incumbent President Jair Bolsonaro in the October vote. Both men are already in campaign mode, although neither has declared his candidacy.
