Here is a great article. This is one of the best quotes from it:

When we teach our congregations to vote for one candidate merely out of fear of the other, we have already accepted a government that allows too much power in one person’s hands, or in the hands of captors who are using candidates as mascots. We already admit they have too much power; when we vote for this current system, therefore, we are condoning it. We must acknowledge the whole system is broken and not just the President.
