In a representative government such as America, voters in the political system are often referred to as "constituents." The term is given to registered voters belonging to a district represented by an elected official. Another term for voters is "electors," which indicates that those casting votes are electing the representative.
The word "constituent" comes from the root word "constitute." The verb means to make up, compose, form or establish. In the case of an election, a body of voters is formed for appointing or electing a representative. This body constitutes the people represented by the chosen individual.
Most voters in the United States identify with political parties such as the Democrats or Republicans, but others maintain autonomy and call themselves independent voters. Registered voters casting ballots from outside their home jurisdiction are known as absentee voters.
