In the United States, third parties are also called minor parties because they "have never won a presidential election."
While third parties in the United States have occasionally won seats in Congress and state legislatures, they have never succeeded in winning a presidential election. As a result, they are often referred to as minor parties because they have a relatively small impact on national politics compared to the two major parties, the Democrats and Republicans. Third parties in the United States often draw attention to social issues and advocate for specific policy positions, but they have historically struggled to gain widespread support and compete with the major parties in national elections.
