Joe Biden's Path to Presidency: From Senator at 30 to President at 79

Joe Biden became a senator at the age of 30 because he was elected to represent Delaware in the U.S. Senate in 1972. He served as a senator for 36 years before being elected as vice president in 2008 and 2012. He then ran for president in 1988 and 2008, but was unsuccessful. He finally won the presidency in 2020 at the age of 79, after serving as vice president for eight years under President Barack Obama. The timing of his presidency is a result of his political career, the opportunities available to him, and the outcomes of various elections.
