The Common Ground Freedom Network welcomes open-minded people from any political party, working together to promote freedom, which is "beyond left and right", as shown in this diagram, which illustrates how freedom is different from either "left or right": http://www.progress.org/banneker/posquiz.html
At this time, we've merged with the Philosophy and Humanity Meetup group, which is for informal discussions about philosophy, and includes some aspects of political philosophy, such as philosophy of individual rights, philosophy of economics, and philosophy of ethics (any political philosophy should be based on a clear view of ethics).
The Philosophy and Humanity Meetup group meets on the 1st Sunday of each month, 1:30-3:30. We usually go out to dinner afterwards. Also, we sometimes go to movies as a group, and have some other activities; there are also other possibilities, such as museums, historic sites, etc. If you're interested, contact us through the Philosophy and Humanity Meetup group: http://www.meetup.com/philosophy-and-humanity
