Roosevelt, who was the only president (1933–45) to be elected to the White House four times, and Barack Obama, who was the first African American president (2009–17). Other Democratic presidents include John F. Kennedy, Jimmy Carter, Bill Clinton, and Joe Biden. Hillary Clinton made history in 2016 as the first woman to win the presidential nomination of a major U.S. political party, though she ultimately lost the election.
