Jimmy Carter
Jimmy Carter served as the 39th president of the United States from 1977 to 1981. The Democratic president lost his reelection campaign to Republican Ronald Reagan, who went on to serve two terms in the White House.
Carter's biography highlights several factors that played a role in his reelection loss, including a short recession and the hostage-taking of U.S. embassy staff in Iran. On the day Carter left office, Iran released 52 Americans, per White House.gov.
Gerald Ford
Gerald Ford was the 38th president of the United States, serving in the White House from 1974 to 1977. He lost his reelection bid to President Jimmy Carter.
Ford became the first unelected president in the country's history after the resignation of President Richard Nixon after the Watergate scandal. According to History.com, Ford pardoned Nixon, a move some assert possibly cost Ford his presidency.
Herbert Hoover
Herbert Hoover was the 31st president of the United States from 1929 to 1933. Hoover lost to Democrat Franklin D. Roosevelt, who went on to complete three full terms in the White House. Within months of Hoover's election, the stock market crashed, leading the country into the Great Depression.

William Howard Taft was the 27th president of the United States from 1909 to 1913, losing his reelection campaign to Democrat Woodrow Wilson, who went on to complete two full terms in office.
Benjamin Harrison
Benjamin Harrison was the 23rd president of the United States from 1889 to 1893. The Republican president lost reelection to Democrat Grover Cleveland.
At first, Harrison replaced Cleveland in the Democrats' 1888 campaign for reelection. However, Cleveland ran again in 1892 and won, making him a two-term president.
Martin Van Buren
Martin Van Buren was the eighth president of the United States and served from 1837 to 1841. Van Buren lost his reelection campaign to William Henry Harrison, who died shortly after becoming president.
John Quincy Adams
John Quincy Adams was the sixth president of the United States from 1825 to 1829. Adams lost reelection to Andrew Jackson.
During his presidential campaign in 1828, opponents of Adams accused him of corruption and "political plunder," according to his White House biography.
John Adams
John Adams was the second president of the United States from 1797 to 1801. Adams was the first one-term president to serve in office, and he lost reelection to Thomas Jefferson.
