Poll suggests Brazil's Bolsonaro would beat Lula by one point in a runoff

SAO PAULO, Sept 8 - A Nexus poll commissioned by BTG Pactual on Tuesday showed for the first time Brazilian right-wing Senator Flavio Bolsonaro slightly ahead of leftist President Luiz Inacio Lula da Silva in a simulated second-round runoff for next month's election, though they remain locked in a so-called technical tie.• If there was a runoff, the eldest son of former President Jair Bolsonaro would receive 46% of voter support compared with 45% for Lula, the poll said.• An August 31 poll had Lula leading Bolsonaro by 46% to 45%.• The result marked Bolsonaro's strongest showing since Nexus began tracking the race in late March, when the two were tied 46%-46%.• In a first-round scenario, Lula would lead with 39% of the votes, followed by Bolsonaro (35%), Augusto Cury (9%), Ronaldo Caiado (4%) and Renan Santos (4%), the poll said.• If no candidate wins more than 50% of valid votes in the first round, the two frontrunners advance to a runoff.• Nexus surveyed 2,002 people from September 4 to 7.• The poll has a margin of error of 2 percentage points -- greater than the expected difference between the candidates in the second round, a statistical tie.• First-round voting is scheduled for October 4, while a second-round runoff would be held on October 25.
