- Fifteen former vice presidents have gone on to become president themselves.
- Some were unexpectedly inaugurated after the president's resignation, assassination, or illness.
Throughout US history, 15 men who served as vice president have gone on to become president themselves.
Some vice presidents had no choice but to assume office due to the death or resignation of their predecessors, like Lyndon B. Johnson after John F. Kennedy's assassination. Others, like Joe Biden, chose to run for president after serving as second-in-command in the White House.
