Some Democrats have publicly expressed that President Joe Biden is simply too old to potentially launch a 2024 reelection bid in the coming months. Biden, who turned 80 years old on November 20th, is the oldest president in U.S. history, achieving that mark when he was inaugurated at age 78 in 2021. Democrats are worried his record old age in office may be a limiting factor if he decides to run again for reelection.
