The modern political party system in the U.S. is a two-party system dominates by the Democratic Party and the Republican Party. These two parties have won every United States presidential election since 1852 and have controlled the United States Congress to some extent since at least 1856.
The Democratic Party is one of two major political parties in the U.S. It is the oldest voter-based political party in the world. Since 1854, American politics has largely been the story of the battle of the Democrats versus their closely matched adversary, the Republican Party.
The Democratic Party since 1912 has positioned itself as the liberal party on domestic issues. The economic philosophy of Franklin D. Roosevelt has shaped much of the party’s agenda since 1932. Democrats have generally been center-left and support social justice, social progressivism, a mixed economy, and the welfare state.
The Republican Party is one of the two major contemporary political parties in the United States of America. Since the 1880s it has been nicknamed the “Grand Old Party” or GOP, although it is younger than the Democratic Party.
Founded in 1854 by Northern anti-slavery activists and modernizers, the Republican Party rose to prominence in 1860 with the election of Abraham Lincoln, who used the party machinery to support victory in the American Civil War. The GOP dominated national politics during the Third Party System, from 1854 to 1896, and the Fourth Party System from 1896 to 1932. Today, the Republican Party supports an American conservative platform, with further foundations in economic liberalism, fiscal conservatism, and social conservatism.
In the United States, the Green Party has been active as a third party since the 1980s. Currently, the primary national Green Party organization in the U.S. is the Green Party of the United States, which has eclipsed the earlier Greens/Green Party USA.
Greens emphasize environmentalism, non-hierarchical participatory democracy, social justice, respect for diversity, peace and nonviolence.
The Libertarian Party was founded on December 11, 1971. It is one of the largest continuing third parties in the United States, claiming more than 331,000 registered voters. They currently have about 144 elected officials, more than any of the other minor parties.
The Constitution Party is a national political party in the United States. It was founded as the U.S. Taxpayers Party in 1992.
The Constitution Party advocates a platform that they believe reflects the Founding Fathers’ original intent of the U.S. Constitution, principles found in the U.S. Declaration of Independence, and morals taken from the Bible.
