A two-party system is a political framework where two major political parties dominate the political landscape. In such systems, these parties typically compete for control of government offices and influence over policy decisions. This structure often leads to a clear choice for voters, as they primarily align with one of the two parties, which can simplify the electoral process. In the United States, the two main parties are the Democratic Party and the Republican Party. This system can create stability and predictability in governance, but it may also limit the representation of diverse viewpoints, as smaller parties often struggle to gain traction in elections.
