To what extent should members of Congress adopt representation tactics more in line with the delegate or trustee model of representation than those they currently employ?

Democratic theory presupposes at least some link between the decisions made by elected officials and the policy preferences of their constituents. How strong that relationship should be, however, depends in part on the ability of those constituents to make informed political judgments and decisions. In an essay, discuss how strong you think that link should be. First, describe to what extent Bartels argues that this link actually exists between members of Congress and the public, at least on matters of income inequality. Then, draw upon the selections from Berelson et al., Popkin, and Bartels to discuss whether the average citizen is sufficiently interested, knowledgeable, and engaged to make informed political judgments and decisions. Given your description of the political capacities of the average citizen, is the level of responsiveness detailed by Bartels appropriate? To what extent should members of Congress adopt representation tactics more in line with the delegate or trustee model of representation than those they currently employ?
