Simple microeconomics shows the fallacy of most voter fraud

It was just prior to my first midterm exam in microeconomics when I learned that a company ideally should keep producing so long as it can make money by doing it. In other words, once the marginal cost of production exceeds the marginal revenue from that production, it is quitting time. And this concept applies beyond the world of production: When the potential cost of doing something (like voting) outweighs the potential benefit from that activity, then that activity makes no sense to do anymore.
