Two-party system
Third parties, meaning a party other than one of the two dominant parties, are possible in two-party systems, but they are often unlikely to exert much influence by gaining control of legislatures or by winning elections. While there are occasional opinions in the media expressed about the possibility of third parties emerging in the United States, for example, political insiders such as the 1980 presidential candidate John Anderson think the chances of one appearing in the early twenty-first century is remote. A report in "The Guardian" suggested that American politics has been "stuck in a two-way fight between Republicans and Democrats" since the Civil War, and that third-party runs had little meaningful success.
Party system
First Party System: This system can be considered to have developed as a result of the factions in the George Washington administration. The two factions were Alexander Hamilton and the Federalists and Thomas Jefferson and the Democratic-Republican Party. The Federalists argued for a strong national government with a national bank and a strong economic and industry system. The Democratic-Republicans argued for a limited government, with a greater emphasis on farmers and states' rights. After the 1800 Presidential election, the Democratic-Republicans gained major dominance for the next twenty years, and the Federalists slowly died off.
