RIO DE JANEIRO (AP) — Brazilian President Jair Bolsonaro’s apparent acknowledgment of his electoral defeat may have helped avert political chaos. Still, he has not directly conceded the race and is not discouraging die-hard supporters who have staged protests across the country and asked the military to step in and keep him in power. Meanwhile, leftist President-elect Luiz Inácio Lula da Silva is facing considerable challenges. The 77-year-old former union boss will need to right a wobbly economy and confront still-formidable conservative forces in many states and Congress.
