| Major political parties of the United States, and the time spans during which they were nationally prominent, are charted here. The Founding Fathers created no provisions for political parties in the U.S. Constitution, believing that institutional regulation would foster corruption and inhibit the public’s ability to freely judge issues and candidates. A two-party system has come to dominate the country’s politics, and since the mid-19th century the Democratic and Republican parties have been most prominent. |
