The Democratic National Convention (DNC) 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 officially nominate a candidate for president and vice president, adopt a comprehensive party platform, and unify the party. Pledged delegates from all fifty U.S. states, the District of Columbia, and the American territories, and superdelegates which are unpledged delegates representing the Democratic establishment, 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. Since the 1980s, national conventions have become mostly inaugural events for the winning candidate, since winners are announced long before the convention. In 2020, both major parties, and many minor parties, replaced their usual in-person conventions with virtual programs due to the COVID-19 pandemic.
