Independent

An independent is a politician who is not affiliated with any political party. Independents may hold a centrist viewpoint between those of major political parties, or they may have a viewpoint based on issues that they do not feel that any major party addresses. Other independent candidates are associated with a political party and may be former members of it, but are not able to stand under its label. A third category of independents are those who may belong to or support a political party but believe they should not formally represent it and thus be subject to its policies.
