Final answer:
The delegate model of representation involves representatives acting in accordance with their constituents' opinions when voting on bills, instead of relying on their personal views.
Step-by-step explanation:
When a representative relies on the opinions of their constituents to make decisions on how to vote on a bill, regardless of their own feelings on the matter, this aligns with the delegate model of representation. In this model, the representative acts primarily as a mouthpiece for the wishes of the constituents, setting aside personal judgment in favor of the majority viewpoints held within their district. Conversely, the trustee model of representation allows for the representative to exercise their judgment and expertise, making decisions they believe to serve the best interests of the constituents, even if contrary to the constituents' immediate desires.
