WASHINGTON (AP) — President Joe Biden is working to quell Democratic anxieties over his unsteady showing in his debate with ex-President Donald Trump. He’s not the debater he used to be, Biden conceded at a rally Friday in North Carolina. But he added that “The choice in this election is simple: Donald Trump will destroy our democracy. I will defend it.” Democratic lawmakers are expressing plenty of concern but sticking by him for now. Meanwhile, Trump’s attacks on critics and his policy falsehoods served as a reminder of the daily turbulence of his Republican presidency.
