Political affiliation is an association with a set of ideas, principals and morals of a political group. Affiliation could either mean one shares the same views or one is registered with a party.
Since no one is born with a political affiliation, it is acquired through experience and association with others known as political socialization. Political preferences are most commonly developed from one's parents. Other factors include teachers, friends and mass media. The largest share of Americans identify as Independent, which is the fastest-growing political affiliation. A few political groups are Republicans, Democrats, Tea Party members and Socialists. Communists and Libertarians also exist as political orientations.
