A primary challenge occurs in U.S. politics when an incumbent elected official is challenged in an upcoming primary election by a member of his own political party. Such events, known informally as "being primaried," are noteworthy and not frequent in the United States, as tradition dictates that members of a political party support officeholders of the same party, both for party unity and to minimize the possibility of loss of the seat to an opposing party.
