The electoral connection thesis asserts

The electoral connection thesis asserts that elections serve to constrain the elected officer’s activities in Washington. The incumbent who fails to represent constituent interests and preferences is presumed to gain less electoral support in the next election. In this regard, it is reasonable to believe that elected officers beholden for the desire for holding office unquestionably fear losing elections by taking positions against the preferences of constituencies on important issues. How do voters have information concerning legislative voting sufficient to keep their representatives accountable by rewarding and/or punishing them on the basis of ideological representation in Congress? Do you think that reelection consideration is the principal theoretical ground to link constituent preferences to legislative voting behavior? Is there something else besides self-interest that might explain the voting patterns in Congress?
