This morning on Fox and Friends, Geraldo Rivera said that he thinks voting, Soviet style, should be mandatory. In other words he believes that the failure to vote should be legally punishable, presumably with fines or imprisonment. As discussed here with regards to Obamacare, an activity cannot be both mandatory and a right since having the right to do something, by definition, implies a right not to do it. In other words, one cannot both be legally obliged to vote and have a right to vote.
