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

The Democratic Party and the Republican Party are recognized as the two major political parties in the United States due to their significant influence on national politics, their extensive organizational structures, and their ability to win the vast majority of elections at various levels of government. These parties have dominated the political landscape for many decades, shaping public policy and national discourse.

The Democratic Party traditionally represents a more liberal ideology, advocating for social justice, environmental protection, and a strong role for government in economic regulation. In contrast, the Republican Party typically embodies conservative principles, emphasizing limited government, free-market capitalism, and individual liberties. This ideological division contributes to a robust and often contentious political debate, reinforcing their dominance in the electoral process.

Other parties mentioned in the options, such as the Green Party, Libertarian Party, Socialist Party, and others, while they may have specific platforms and local influence, do not have the same level of national presence or the historical significance of the Democratic and Republican parties in the context of U.S. politics.
