If this is a true or false question, the answer is "true."
It is true that the US has never experienced a period in which a single political party existed and there was little if any political conflict.
On the contrary, political parties have always existed in the history of the United States. First, it started with two political factions: Federalists with people like James Madison, Alexander Hamilton, and John Jay; and Antifederalists with people like Thomas Jefferson or Samuel Adams.
Throughout the history of the United States, there have always been different political parties, but the dominant political forces have always been Republicans and Democrats, creating a bipartisan political system.
