Final answer:
Members of Congress should balance between voting their own conscience and following the will of the people who elected them into office. This is known as the politico model of representation, where representatives act as either delegates or trustees based on political circumstances and the best interest of the constituency or the nation.
Step-by-step explanation:
The decision on whether members of Congress should vote their own conscience or follow the will of the people who elected them into office can be understood in the context of the delegate/trustee split in political representation. While some representatives believe in acting as delegates and enacting the wishes of their constituents, others take a trustee approach and exercise their own judgment based on what they believe is in their constituents' best interests. In reality, most representatives adopt a balance between the two, known as the politico model of representation, where they act as either a delegate or trustee depending on the political circumstances and what they believe serves the constituency or the nation best.
