What is the American two party system called?

The American two-party system is often referred to simply as the "two-party system." It primarily consists of the Democratic Party and the Republican Party, which dominate the political landscape. This system is characterized by the tendency of electoral politics to favor these two parties, making it challenging for third parties to gain traction in elections. The structure is reinforced by winner-takes-all electoral mechanisms and the First Past the Post voting system.
