Question

Quizplus · Accepted Answer

Members of the House of Representatives are more likely to use the delegate style of representation because they are elected for only two-year terms and are therefore more responsive to the preferences of their constituents. They are also more likely to be influenced by pressure from interest groups and have less autonomy than members of the Senate or other officials.
