Explanation: American electoral politics has been dominated by two major political parties since shortly after the founding of the republic. Since the 1850s, they have been the Democratic Party and the Republican Party. Since the last major party realignment in the mid-20th century, the Democratic Party has been the center-left and liberal party, and the Republican Party has been the center-right and conservative party. Since the 1990s, both the Republican and Democratic parties have shifted further apart. 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.[1] The largest third party since the 1980s has been the Libertarian Party. Besides the Constitution, Green, and Libertarian parties, there are many other political parties that receive only minimal support and only appear on the ballot in one or a few states.
