Reasoned Voting - Part 2

In their attempts to convince others to vote for a particular candidate, many people are using arguments that invoke the fundamental principles of reason from the philosophical sciences. Unfortunately, many of these invocations use these arguments in an improper way. I addressed some of the most common in a recent article titled Reasoned Voting. I recently came across another use of a principle of reason in support of voting for a particular candidate which, in the interest clear reasoning, I would like to address in this follow-up to that article. The principle is known as "Double-Effect."

The Process of Subsidiarity

Many critics of distributism claim that what we want to achieve would require the expansion of state power and that we really want an all powerful state. What we actually advocate is the decentralization of government power. We want to distribute the various powers of government as close to the local level as can be practically achieved. This is because we promote the principle known as "subsidiarity." Subsidiarity states that,

"A community of a higher order should not interfere in the internal life of a community of a lower order, depriving the latter of its functions, but rather should support it in case of need and help to coordinate its activity with the activities of the rest of society, always with a view of the common good."                                      - Pope St. John Paul II

That sounds great, but how would it work?
