Joe Biden's failure to keep Donald Trump out of office haunts his legacy. Biden's single term will now be bookended by his rival's presidencies. He faced historic challenges, including the Capitol assault and the shattered economy due to Covid. Despite his achievements, his popularity suffered due to the chaotic US withdrawal from Afghanistan and inflation caused by his pandemic stimulus. Biden believed he was the only person who could beat Trump again, but age became a battle he couldn't win. In his farewell speech, he warned of a dangerous 'oligarchy taking shape in America' but also highlighted the magic of America.
