Why Citizens Should Vote: A Causal Responsibility Approach

Why should a citizen vote? There are two ways to interpret this question: in a prudential sense, and in a moral (or quasi-moral ) sense. Under the first interpretation, the question asks why—or under what circumstances—it is in a citizen's self-interest to vote. Under the second interpretation, it asks what moral (or quasi-moral) reasons citizens have for voting. I shall mainly try to answer the moral version of the question, but my answer may also, in some circumstances, bear on the prudential question. Before proceeding to my own approach, let me briefly survey alternatives in the field.
