I get the point you are making but wouldn't fly as a democratic principle.

Wisdom comes with age but there are exceptions. In Biden's case, the US people have elected the president they deserve or, more particularly, the party caucus system has delivered the candidate that it deserved.

The above said, the US system is weird and thus generates weird or inappropriate politicians.
