Final answer:
Constituents trust elected officials to represent them, which can be done by following either the delegate model or the trustee model of representation.
Step-by-step explanation:
Constituents have placed trust in elected officials to represent them by addressing their concerns and acting in their best interests. Elected representatives can adopt different models of representation: the delegate model, where they act according to the expressed wishes of their constituents, and the trustee model, where they use their own judgment to make decisions they believe are in the best interest of the people, even if that goes against the constituents' immediate preferences. This dual approach reflects the understanding of Edmund Burke, a prominent figure in the history of political thought, who emphasized the importance of legislators using good judgment while considering the will of those they represent.
