Congressional campaigns are often run by the political parties-- for example, there is a Democratic Senatorial Campaign Committee (DSCC) and a Republican Senatorial Campaign Committee (RSCC), each of which raises money and allocates resources to help members of its party get elected (or re-elected) to the Senate. Each committee has its own chairman or chairwoman, who is sometimes a former member of congress, or it can be a major figure in the party who has a background in fundraising and is well-respected for his or her political knowledge. Also, in addition to the national committees, the candidates for both the Senate and the House have their own local campaign operation; it is run by a campaign manager, whose job it is to support the senator or representative's run for office.
