 The delegate and the trustee conception of political representation place competing and contradictory demands on the behavior of representatives. [For a discussion of the similarities and differences between Madison’s and Burke’s conception of representation, see Pitkin 1967, 191–192.] Delegate conceptions of representation require representatives to follow their constituents’ preferences, while trustee conceptions require representatives to follow their own judgment about the proper course of action. Any adequate theory of representation must grapple with these contradictory demands.
