 Senator Barack Obama of Illinois was selected as the nominee, becoming the first African-American to secure the presidential nomination of any major political party in the United States.
 However, due to a close race between Obama and Senator Hillary Clinton of New York, the contest remained competitive for longer than expected, and neither candidate received enough pledged delegates from state primaries and caucuses to achieve a majority, without endorsements from unpledged delegates (superdelegates).

In American politics, a superdelegate is an unpledged delegate to the Democratic National Convention who is seated automatically and chooses for themselves for whom they vote.
 These Democratic Party superdelegates (who make up just under 15% of all convention delegates) include elected officials and party activists and officials.
 Democratic superdelegates are free to support any candidate for the presidential nomination.
 This contrasts with convention "pledged" delegates who are selected based on the party primaries and caucuses in each U.S. state, in which voters choose among candidates for the party's presidential nomination.
 Moreover, superdelegates are permitted to participate in the primary elections as regular voters.
