The question of how to make Congress more accountable and responsive has been examined by several authors who have made some interesting proposals. Some of the following may be good jumping off points for a response to this assignment.
Political scientist Larry Sabato, in his book A More Perfect Constitution, suggested increasing the size of the House of Representatives from 435 to 1,000 members. This would compress the size of congressional districts, allowing representatives to be closer to the voters who elect them. He also suggested that all former presidents and vice-presidents be made senators for life; in this role they would be able to represent the perspective of the whole nation rather than individual states.
In The Reclamation of the U.S. Congress, a policy report from the University of Texas, it was suggested to reform congressional committees so that they are composed of members from across both chambers. This would encourage greater deliberation and allow Congress to better divine popular needs.
Adam Carrington, a professor at Hillsdale College, has suggested ending the filibuster, the rule by which a minority of 41 senators can block legislation. According to Carrington, this has the effect of "changing majority rule into a de facto minority veto." By ensuring the Senate could not block legislation favored by the majority, the entire branch would become more responsive to the democratically expressed desires of the body politic.
