The Democratic National Committee coordinates most of the activities of the Democratic Party in all 50 United States. Since Andrew Jackson 's inauguration in 1829, there have been 17 Democratic presidents, the most recent (and current) being former Vice President Joseph R. Biden Jr. (D-DE) who took office as President of the United States in 2021.
Since the 1930s, a critical component of the Democratic Party coalition has been organized labor. Labor unions supply a great deal of the money, grassroots political organization, and voting base of support for the party. Union membership in the United States has declined from an all-time high in 1954 of 35% to a low of 11% in 2015.
The first two major parties in the United States were the Federalist Party and the Democratic-Republican Party. The Federalists experienced success in the 1790s but lost power in the 1800 elections and collapsed after the War of 1812. Many former Federalists, including John Quincy Adams, became members
When James Monroe was elected President of the United States, the Federalists died out. There was an "Era of Good Feelings" of one-party rule by the Democratic-Republicans. In the United States presidential election, 1824, four different men ran for President, all as Democratic-Republicans. John Quincy Adams was elected.
