Voting, Right, Responsibility

In many contexts, Right and Responsibility are conjoined concepts.  One in which they are not is Modern Political Philosophy, in which Right is typically a cardinal principle, while Responsibility is hardly ever more than vaguely alluded to. For example, in the U. S. Constitution, there is a Bill of Rights, but no Bill of Responsibilities.  Correspondingly, there is a Right to Vote, but no Responsibility to Vote.  Now, the occasionally proposed making voting mandatory, with 'none of the above' as an option, has usually been met with a hostility that is groundless, even though such a measure would make voter engagement and candidate responsiveness routine in the American political process.  That possibility only exposes the significant deficiencies in actual approximations to 'Democracy' in the American Experiment.
