Since the 1850s, they have been the Democratic Party and the Republican Party. This two-party system is based on laws, party rules and custom, not specifically outlined in the US Constitution. Several third parties also operate in the U.S. and from time to time elect someone to local office. The largest third party since the 1980s has been the Libertarian Party.
About Political parties in the United States in brief

The Second Party System operated from the late 1820s to the mid-1850s. Two major parties dominated the political landscape: the Whig Party, led by Henry Clay, that grew from the Republican National Party; and the Democrats led by Andrew Jackson, who supported the primacy of the Presidency over the other branches of government. The last major party realignment was in the early 1990s, when the Democrats became the center-left and liberal party and the Republicans became the right-wing and conservative party. The United States Constitution is silent on the subject of political parties. It does not mention the term ‘party’ in the Declaration of Independence, nor does it mention the concept of a ‘party system’ or a ‘two-party’ system in the First Amendment to the US constitution. In addition, George Washington, was not a member of any political party at the time of his election or throughout his tenure as president. He hoped that political parties would not be formed, fearing conflict and stagnation, as outlined in his Farewell Address. Nevertheless, the beginnings of the American two- Party system emerged from his immediate circle of advisers, including Alexander Hamilton and James Madison, who wrote the aforementioned Federalist Papers against political factions. Hamilton and Madison ended up being the core leaders in this emerging party system. The Federalists survived their refusal to support the Federalists in the 1800s and the War of 1812 in the Northeast.
