List of third party performances in United States elections

This is a list of third party performances in United States elections.

In the United States it is rare for third party and independent candidates, other than those of the six parties which have succeeded as major parties (Federalist Party, Democratic-Republican Party, National Republican Party, Democratic Party, Whig Party, Republican Party), to take large shares of the vote in elections.

In the 58 presidential elections since 1788, third party or independent candidates have won at least 5.0% of the vote or garnered electoral votes 12 times (21%); this does not count George Washington, who was elected as an independent in 1788–1789 and 1792, but who largerly supported Federalist policies and was supported by Federalists. Occasionally, a third party becomes one of the two major parties through a presidential election (the last time it happened was in 1856, when the Republicans supplanted the Whigs, who had withered and endorsed the ticket of the American Party): such an election is called a realigning election, as it causes a realignment in the party system; according to scholars, there have been six party systems so far. Only once one of the two major parties came third in an election, but that did not cause a realignment (in 1912 the Progressive Party surpassed the Republicans, but the party quickly disappeared and the Republicans re-gained their major party status). The last third party candidate to win one or more states was George Wallace of the American Independent Party in 1968, while the most recent third party candidate to win more than 5.0% of the vote was Ross Perot, who ran as an independent and as the standard-bearer of the Reform Party in 1992 and 1996, respectively.
