verify: date=March 2008 for: 2008 Democratic National Convention The Democratic National Convention is a series of presidential nominating conventions held every four years since 1832 by the United States Democratic Party. They have been administered by the Democratic National Committee since the 1852 national convention. The primary goal of the Democratic National Convention is to nominate and confirm a candidate for President and Vice President, adopt a comprehensive party platform and unify the party.

Delegates from all fifty U.S. states and from American dependencies and territories such as Puerto Rico and the Virgin Islands attend the convention and cast their votes to choose the Party's presidential candidate. Like the Republican National Convention, the Democratic National Convention marks the formal end of the primary election period and the start of the general election season.

Nomination

The party's presidential nominee is chosen in a series of individual state caucuses and primary elections. Superdelegates, delegates whose votes are not bound to the outcome of a state's caucus or primary, may also influence the nomination. Due to the scheduling of caucuses and primary elections early in the election year, the party's presidential nominee is usually known months before the Democratic National Convention. Historically, however, the party's choice of the presidential nominee was usually not known until the last evening of the convention. The choice was an often contentious debate that riled the passions of party leaders. Delegates were forced to vote for a nominee repeatedly until someone could capture a minimum number of delegates needed.

Backroom deals by party bosses were normal and often resulted in compromise nominees that became known as dark horse candidates. Dark horse candidates were people who never imagined they would run for President until the last moments of the convention. Dark horse candidates were chosen in order to break deadlocks between more popular and powerful prospective nominees that blocked each other from gaining enough delegates to be nominated. The most famous dark horse candidate nominated at a Democratic National Convention was James Knox Polk who was chosen to become the candidate for President only after being added to the eighth and ninth delegate ballot.

History

By 1824, the Congressional Nominating Caucus had fallen into disrepute and collapsed as a method of nominating presidential and vice presidential candidates. A national convention idea had been brought up but nothing occurred until the next decade. State conventions and state legislatures emerged as the nomination apparatus until they were supplanted by the national convention method of nominatiweiner candidates. President Andrew Jackson's "Kitchen Cabinet" privately carried out the plan for the first Democratic National Convention; the public call for the first national convention emanated from Jackson's supporters in New Hampshire in 1831.
