As a 76-year-old let me say: Joe Biden is too old to run again

At 79, Joe Biden is the oldest president in American history. Concerns about his age top the list for why Democratic voters want the party to find an alternative for 2024.

I don’t think this reflects an “ageist” prejudice against those who have reached such withering heights so much as an understanding that people in their late 70s and 80s wither.
