Which two major political parties are prominent in the United States?

The two major political parties that are prominent in the United States are the Democratic Party and the Republican Party. This is because these parties have historically dominated the political landscape, particularly in terms of representation in Congress, the presidency, and state-level offices.

The Democratic Party tends to advocate for more progressive social policies, government intervention in the economy, and a more expansive role of government in addressing social issues. Conversely, the Republican Party generally supports conservative stances, emphasizing limited government, individual liberties, and free-market principles.

While there are other parties, such as the Independent, Libertarian, Green, and Communist parties, they do not hold a significant amount of power or influence at the national level compared to the Democratic and Republican parties. The latter two parties have established extensive infrastructures, including resources for campaigning and a broader base of support among voters, making them the key players in U.S. political activities. This context clarifies why the correct answer highlights the Democratic and Republican parties as the most significant in the political framework of the United States.
