Take a look at Vox Nova. From the group:
We are writing to humbly request your help in getting the word out about our new Catholic social/political blog. We are a group of faithful Catholics of very different political persuasions–from libertarians to distributists, from capitalists to anarchists, from conservatives to collectivists. We are united in our conviction that Jesus Christ is the center of the universe and the full revelation of humanity to itself. As Catholics committed to the tradition and magisterium of the Church, we seek to provide smart and informed commentary and debate on culture, society and politics from the Catholic perspective. Because of the diversity of the contributers (mothers, professors, students, fathers, laborers, immigrants), this blog is sure to be uniquely interesting and lively.The new blog is Vox Nova. Please take a moment to stop by. We have already set-up resources on the papal social encyclicals, pro-life campaigns, and Catholic organizations and ministries. Also, we have a "purpose" post in place describing the aim of the blog.
