Brazilian presidential front-runner Luiz Inacio Lula da Silva has gained steam in the final stretch of the campaign, opinion polls show, and could defeat incumbent Jair Bolsonaro in the first round on Sunday – if his base shows up to vote in full force.
Still, rising voter abstention, especially among less affluent Brazilians who lean toward leftist Lula, could mean the election goes to a second round. If no one among the 11 candidates gets more than 50% of votes, excluding blank and spoiled ballots, the two front-runners - almost certainly Lula and Bolsonaro - would go to an Oct. 30 run-off vote.
