The presidential debate was a re-run that featured two candidates with a combined age of 159, but it went especially poorly for one of them, President Joe Biden.

Already fighting voter concerns about his age, Biden, 81, was halting and seemed to lose his train of thought Thursday night, sparking quick concerns among Democrats about the man they hope will keep former President Donald Trump from returning to office. For his part, Trump made repeated false claims and provocative statements. But Trump seemed smoother and more vigorous than Biden, who is only three years older than the Republican ex-president.
