The United States has what is known as a two party system
Nominating people for public office is a political party's primary duty. Parties educate the populace, pique their curiosity, and encourage engagement in civic affairs.
A political party serves as a "bonding agent" in politics to secure the success of its candidates and elected officials. In a two-party system, there are only two political parties that actually stand a chance of winning elections.
A political party is made up of people who band together to run the government, win elections, and shape public policy.
