The US President believes that the only thing that age brings is wisdom.
There are growing calls among Democrats to nominate another candidate to replace Biden after his failure in debate with Donald Trump. Theoretically, the party will have such an opportunity at the congress in August, but in practice it will be difficult to remove the primaries-winning candidate from the race if he does not refuse to participate. At the same time, Biden says he intends to stay in the race.
