He graduated from Eureka College in 1932 and worked as a sports commentator on several regional radio stations. In 1980, Reagan won the Republican presidential nomination and defeated the incumbent president, Jimmy Carter. At 69 years, 349 days of age at the time of his first inauguration, Reagan was the oldest person to assume the U.S. presidency, a distinction he held until 2017, when Donald Trump was inaugurated at age 70 years, 220 days. Reagan faced former vice president Walter Mondale when he ran for re-election in 1984 and defeated him, winning the most electoral votes of any U.S. president, 525, or 97.6% of the 538 votes in the Electoral College. When Reagan left office in 1989, he held an approval rating of 68%, matching those of Franklin D. Roosevelt, and later Bill Clinton, as the highest ratings for departing presidents in the modern era.
