What kind of political system do we have and how many political parties are there?

The political system in the United States is a federal republic characterized by a representative democracy. It primarily operates under a two-party system dominated by the Democratic Party and the Republican Party. While there are other political parties, such as the Libertarian Party and the Green Party, they hold significantly less power and representation in comparison to the two major parties. This two-party structure influences election dynamics and legislative processes across the country.
