What are party or floor leaders?
The political parties in the House elect leaders to represent them on the floor, to advocate their policies and viewpoints, to coordinate their legislative efforts, and to help determine the schedule of legislative business. The party or floor leaders also serve as spokespersons for their parties and for the House as a whole. Because of its larger membership, the House required Majority and Minority Leaders in the 19th century to expedite legislative business and to keep their parties united.
