Is Joe Biden too old to win another go in the White House? And could his son derail his campaign? The Americast team talks through the challenges the president is facing in the run-up to the next election.

Barack Obama's former spokesperson and podcaster Tommy Vietor gives us his thoughts on Biden's achievements and viral moments, as well as his 2024 chances, with some critics obsessed by his age and sceptical about Vice President Kamala Harris.

And the gang tries to guess the Republican presidential candidate from the songs that supposedly "stir their souls".

HOSTS: • Justin Webb, Radio 4 presenter • Sarah Smith, North America editor • Marianna Spring, disinformation and social media correspondent
