Imagine you succeed in persuading a large number of nonvoters to vote. Do you have some reason to suspect they would make better decisions, i.e. choose better candidates, than people who currently vote? I could never understand why voting per se was held to be a virtue. If you don't care or don't know what you're doing, why should I want you to vote?
