Before the era of presidential primary elections, political party conventions were routinely brokered. The Democratic Party required two-thirds of delegates to choose a candidate, starting with the first Democratic National Convention in 1832, and then at every convention from 1844 until 1936. For the Democrats a brokered convention was considered possible, as it was unclear for a time whether either of the two frontrunners, Senator Barack Obama and Senator Hillary Clinton, would be able to win a majority of pledged delegates before the convention. Until 1984 two state conventions were held in gubernatorial years, one for state affairs in September and one for sending delegates to the national Democratic convention. The permanent organs of the party are largely independent of the temporary ones. In 1876, however, the state Democratic party continued to focus its attention on the concerns of the Civil War era. In fact, the majority of the delegates to the state Democratic convention were Confederate veterans. Democratic voters were often white landowning agrarians, manufacturers, lumbermen, bankers, shippers and railroad men, and Protestant 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. Prior to 1940, nomination for president was required, not by a simple majority, but by ⅔ of the total delegate votes cast. The first national convention of the Democratic Party began in Baltimore on May 21, 1832. In that year the 2/3 rule was created, requiring a 2/3 vote to nominate a candidate, in order to show the party's unanimous support of Martin Van Buren for vice president. 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.

In that year the 2/3 rule was created, requiring a 2/3 vote to nominate a candidate, in order to show the party's unanimous support of Martin Van Buren for vice president. The Democratic National Convention (DNC) is a series of presidential nominating conventions held every four years since 1832 by the United States Democratic Party.

The Democratic Party is one of the two major contemporary political parties in the United States, along with the Republican Party to its right. The Democratic Party traces its origins to the inspiration of the Democratic-Republican Party, founded by Thomas Jefferson, James Madison, and other influential opponents of the Federalists in 1792. Once the first ballot, or vote, has occurred, and no candidate has a majority of the delegates' votes, the convention is then considered brokered; thereafter, the nomination is decided through a process of alternating political horse-trading, and additional re-votes. For the Democrats a brokered convention was considered possible, as it was unclear for a time whether either of the two frontrunners, Senator Barack Obama and Senator Hillary Clinton, would be able to win a majority of pledged delegates before the convention. Although the term brokered convention is sometimes used to refer to a convention where the outcome is decided by superdelegate votes rather than pledged delegates alone, this is not the original sense of the term. For the Democrats a brokered convention was considered possible, as it was unclear for a time whether either of the two frontrunners, Senator Barack Obama and Senator Hillary Clinton, would be able to win a majority of pledged delegates before the convention. DELEGATE SELECTION PRIMARY. This is the oldest type of presidential primary-one going back to the 1904 election, at which time Florida became the first state to authorize the use of a so-called direct primary election to choose the state's delegates to the Democratic National Convention. In 1996, however, no Democratic primary was of the LOOPHOLE type. The GOP, meanwhile, has no national party rules against the use of the LOOPHOLE type and a handful of states did use it for the choosing of delegates to the Republican National Convention in 1996.
