To finish this series I thought I would put up a list of resources. These books range from those supporting conservative politics to liberal politics, and from supporting Christians involvement in government to supporting the idea that we should stay away from worldly politics. Some deal specifically with the issues we have been discussing while others only touch on related subjects.
Here are a few more links on the topic.
This is a very short list. This is a subject that has been extensively covered from a variety of perspectives. If it interests you I would like to hear what you think.
