Which statement most accurately describes the role of the democratic and republican parties in U S politics

The two parties have dominated U. S politics for more than 150 years.

Explanation:

The Democratic Party and the Republican Party are the two main political parties in the United States, and the only ones in practice that have some kind of relevance at the national level. Both parties have their origin in the political parties originating in the 1700s, and have evolved according to the country's own history.

Thus, the Democratic Party, founded in 1828, defends the idea of a strong and comprehensive federal government with specific powers regarding social security, participation in the economy and a rather soft foreign policy in the face of international conflicts. It is the main exponent of liberalism in the country. Its voters are found mostly in large urban areas, and demographically the party tends to represent the country's ethnic and cultural minorities.

Instead, the Republican Party, founded in 1854, advocates the idea of a reduced federal government, with strong powers by the states and limited participation in the country's economy and social environment. It is, in short, the party that represents conservatism in the United States, and its voters tend to be inhabitants of rural areas or inner cities, and to be mostly white.
