As President Joe Biden is expected to announce his re-election campaign soon, skeptics are once again raising concerns about his age. If he wins a second term, Biden will begin it at the age of 82, older than any previous U.S. President. Despite this, many Americans believe he stands a good chance of being re-elected, especially as he has already secured the Democratic nomination. Although Biden's approval rating has not been strong, he has achieved policy accomplishments such as steering the country out of the COVID-19 pandemic and overseeing economic recovery. Regardless, concerns remain over whether he is too old to run for the presidency again. Some suggest the age issue could be resolved by tapping a successor, as Warren Buffet and Charlie Munger of Berkshire Hathaway have done with Canadian Greg Abel. Whether or not Biden addresses these concerns, he has already overcome skepticism about his electability once before, becoming the oldest president ever elected to the U.S. presidency.
