Step-by-step explanation:
The correct answer is e. political strategist. In Congress, a member can decide how to vote on items using several different models of representation. These include being a trustee, a delegate, or a politico. In the trustee model, the legislator uses their own judgment and knowledge of policy to decide what is in the best interests of their constituents. In the delegate model, the legislator enacts the wishes of their constituents. In the politico model, the legislator balances between being a delegate and a trustee based on rational political calculations.
Political strategist, on the other hand, is not a way in which a member of Congress can decide how to vote on items. This option is not a model of representation, but rather refers to a person who develops and executes political strategies for candidates or political parties.
