President Joe Biden's presidency ends with a mixed legacy as his former political rival, Donald Trump, is about to be inaugurated as president. Trump’s return underscores Biden's inability to shift the nation's trajectory, despite Biden's successes in securing bipartisan deals and rallying allies. Only a quarter of Americans view Biden as a good or great president, a rating lower than Trump’s approval when he left office in 2021 after the Capitol attack and during the pandemic. Biden’s decision to seek re-election, despite doubts about his age, led to a challenging campaign and a failed run of Vice President Kamala Harris.
