Answer: D. The member considers all views before voting on the bill.
In regard to choice A, voting along political party lines would be voting as a partisan.
Choices B and C are similar, in that they are based on the idea of an elected representative as a delegate, serving only to represent the views of those who elected him or her. If the member only cares about getting reelected, that representative likely is just trying to gauge what the district voters want and do that.
Another type of voting is as a trustee, which means listening to the concerns of voters in the district, but then using his or her own judgement in making decisions.
A politico is one who combines all these approaches and considers the party's priorities, district voters' priorities, and his or her own values/priorities.
