Who was the oldest President ever elected prior to Joe Biden?

The correct choice is Ronald Reagan, who was the oldest president elected before Joe Biden. Reagan was 69 years old when he won the presidency in 1980. His age at inauguration marked a significant moment in U.S. history and raised discussions about age and capability in leadership roles.

In contrast, Bill Clinton was elected at 46, George W. Bush at 54, and John F. Kennedy at 43, making them all significantly younger than Reagan at the time of their respective elections. Reagan's presidency is often remembered for the substantial impact he had on both domestic policy and international relations during the Cold War, and his age became a notable point in discussions about the effectiveness and vitality of older leaders.
