Question

what does it mean for a member of congress to represent her constituents as a delegate?
the representative receives substantial
campaign contributions from voters outside
his district
the representative votes according to the
preferences of her constituency
the representative votes based on what she
thinks is best for her constituency
the representative ignores her constituency

Explanation:

In the delegate model of representation, a member of Congress acts as a delegate, which means they vote based on the expressed preferences of their constituents. The other options are incorrect: receiving campaign contributions from outside the district is not related to the delegate role in terms of voting; voting based on what the representative thinks is best is the trustee model; and ignoring the constituency goes against the delegate concept.

Answer:

the representative votes according to the preferences of her constituency
