Democratic Candidates Ranked by Age

Have you seen this chart of the ages of the Democratic Presidents through history compared to today’s potential candidates? They are color coded by their tier in the polls. Biden and Saunders are in the top tier.

As for the old ages, I do not believe that this is such a bad factor. I remember them from the 1980’s. They were just as dumb then as they are now (and just as smart, too.) I rather want to see new ideas than new people.
