What We're Tracking Brazilians vote in the presidential runoff. Current President Jair Bolsonaro and former President Luiz Ignacio Lula da Silva face off in Brazil's Oct. 30 presidential runoff election. Bolsonaro has made a strong recovery in the polls after the first round vote, with da Silva's monthslong 15-point lead decreasing to five points thanks to the government's consistently strong performance on the economy and security — two key issues among Brazilian voters — in recent weeks. The narrow margin in preelection opinion polls and a last-minute scandal over radio airtime may bolster Bolsonaro's ability to contest the election results if he loses, something he has spent much of the year signaling he will attempt in the event he loses. The days following the election, and how the winner and loser handle the outcome, will significantly impact the country's democratic institutions and political polarization in the coming four years.
