Former Vice President Joe Biden has officially entered the 2020 Democratic primary, and has already secured a number of key endorsements from #resistance heavyweights such as celebrity attorney Michael Avenatti.

At 76 years old, Biden would become one of the oldest leaders in world history if elected. The former veep's age could certainly become a factor in the primary campaign, as it is often cited in the context of his creepy "tactile" tendencies. It could also elicit questions about Biden's fitness for office, especially if he is unable to walk without assistance.
