President Joe Biden forcefully tried on Friday to quell Democratic anxieties over his unsteady showing in his debate with former President Donald Trump. Biden's halting delivery and meandering comments, particularly early in the debate, fueled concerns from even members of his own party that at age 81 he's not up for the task of leading the country for another four years. Even before the debate, Biden's age had been a liability with voters, and Thursday night’s faceoff appeared to reinforce the public’s deep-seated concerns before perhaps the largest audience he will garner before ballots are cast. Biden appeared to acknowledge the criticism during a rally in Raleigh, North Carolina, saying ”I don't debate as well as I used to." But he added, “I know how to do this job. I know how to get things done.” Speaking for 18 minutes, Biden repeatedly appeared far more animated than his showing the night before, and he excoriated Trump for his “lies” and campaign aimed at “revenge and retribution.” “The choice in this election is simple," Biden said. "Donald Trump will destroy our democracy. I will defend it." Biden's campaign billed the Raleigh event as the largest-yet rally of his reelection bid in the state Trump carried by the narrowest margin in 2020. He'll then travel to New York for a weekend of big-dollar fundraisers that his campaign now needs more than ever, as it looks to stave off Trump.
