Lula, Flavio Bolsonaro Neck-and-Neck in Brazil Runoff Polls
Brazil is preparing to vote for president.
Two surveys asked people who they would choose if the election reached a final two-person contest.
One survey put Lula slightly ahead, while the other put Flavio Bolsonaro slightly ahead.
Because the differences were within the surveys' margins of error, the candidates were statistically tied.
Lula led Bolsonaro in both surveys when voters were asked about the first round.
The first round is planned for October 4.
If nobody gets more than half of the valid votes, the top two candidates will compete again on October 25.
Bolsonaro's recent polling strength also helped Brazilian financial assets rise because he is viewed as more friendly to markets.
Two polls found President Luiz Inacio Lula da Silva and Senator Flavio Bolsonaro statistically tied in a potential runoff.
BTG Pactual/Nexus gave Lula a 47%-46% lead over Bolsonaro, reversing the previous week's result.
Quaest showed Bolsonaro ahead of Lula by 42% to 40%, after a 41%-41% tie in its prior poll.
In first-round scenarios, Lula led Bolsonaro in both surveys, with 42% to 37% in Nexus and 36% to 31% in Quaest.
Brazil's first round is scheduled for October 4, with a runoff on October 25 if no candidate wins more than 50% of valid votes.
