SAO PAULO (AP) — Luiz Inácio Lula da Silva has done it again: Twenty years after first winning the Brazilian presidency, the leftist defeated incumbent Jair Bolsonaro Sunday in an extremely tight election that marks an about-face for the country after four years of far-right politics. With more than 99% of the votes tallied in the runoff vote, da Silva had 50.9% and Bolsonaro 49.1%, and the election authority said da Silva’s victory was a mathematical certainty. It is a stunning reversal for da Silva, 77, whose 2018 imprisonment over a corruption scandal sidelined him from the 2018 election that brought Bolsonaro, a defender of conservative social values, to power.
