Biden is First President to Turn 80 in Office

Joe Biden turned 80 years old Sunday.

The 46th president of the United States, who, at 78, entered office as the oldest candidate to be elected, now becomes the only sitting president to celebrate his 80th birthday while in power.

He’s also the least articulate due to suffering from dementia.

Biden’s age expects to be a continued talking point for the rest of his term, especially in the context of him potentially running for office again in 2024.

There’s nothing in the U.S. Constitution barring someone from running because of old age – Article II only lists a minimum age of 35 years old.

On average, presidents are sworn in at 55 years old, according to POTUS.com.
