From January 3 to June 3, 2008, voters of the Democratic Party chose their nominee for president in the 2008 United States presidential election. 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. Due to a close race between Obama and Senator Hillary Clinton of New York, the contest remained competitive for longer than expected; neither candidate received enough pledged delegates from state primaries and caucuses to achieve a majority, without endorsements from unpledged delegates (superdelegates).

The presidential primaries actually consisted of both primary elections and caucuses, depending upon what the individual state chose. The goal of the process was to elect the majority of the 4,233 delegates to the 2008 Democratic National Convention, which was held from Monday, August 25, through Thursday, August 28, 2008, in Denver, Colorado. To secure the nomination, a candidate needed to receive at least 2,117 votes at the convention—or a simple majority of the 4,233 delegate votes. This total included half-votes from American Samoa, Guam, and the United States Virgin Islands, in addition to Democrats Abroad, as well as superdelegates—party leaders and elected officials who were not chosen through a primary or caucus.

Obama received enough superdelegate endorsements on June 3 to claim that he had secured the simple majority of delegates necessary to win the nomination, before Clinton conceded the nomination four days later.^[3][4] Obama was nominated on the first ballot at the August convention. He went on to win the general election, and became the 44th president of the United States on January 20, 2009. Clinton went on to serve as Obama's Secretary of State for his first term as president, and the Democratic nominee for president in 2016, losing to Donald Trump. These primaries included the nominees for the next three elections: Obama again in 2012, Clinton in 2016, and Biden in 2020.
