The constituents of a member of Congress are the members of the district that elects him/her. S/he represents these people in the role of a delegate to Congress. In other words, the constituents delegate their member of Congress to make decisions based on their interests and vote for them.

A member of congress who votes based on the wishes of his or her constituents operates in the "delegate" role.

To arrive at this answer, let's break down the different roles of a member of congress:

1. Trustee: A trustee is a member of congress who believes that they were elected to exercise their own judgment and make decisions based on their own expertise and understanding of the issues. They feel that they have been entrusted by their constituents to make the best decisions on their behalf, even if those decisions may not align with the specific wishes of the constituents.

2. Delegate: A delegate is a member of congress who believes that they were elected to represent the specific views and wishes of their constituents. They see themselves as the voice of the people and their primary responsibility is to faithfully represent the interests and opinions of their constituents when voting on legislation.

3. Partisan: A partisan is a member of congress who aligns themselves strongly with a particular political party. They prioritize the interests and goals of their political party over the specific wishes of their constituents or their own personal judgment. Their voting behavior is largely influenced by their commitment to party platforms and agendas.

4. Politico: A politico is a member of congress who operates in a flexible manner, often switching between different roles based on the specific situation. They weigh the opinions and interests of their constituents, party, and personal judgment when making decisions.

Considering these definitions, we can see that a member of congress who votes based on the wishes of his or her constituents falls under the "delegate" role, as they prioritize representing their constituents' views rather than their own judgment or party loyalty.
