Each one should incorporate a range of issues and thinking or they will simply multiply single issue politics. The process naturally empowers the center of the citizenry and marginalizes and many times converts the extreme elements. This process is conflict prevention, not conflict resolution. The whole process mirrors and illustrates our Constitution so that people can start to really understand it and their vital role in it. They learn the skills and the difficulties of being a representative.
Power is shared.
There is an amendment process and a veto process. What the groups do is decided by majority vote but they must be unanimous in determining that the skills were properly used before the votes count. Thus to be effective, to come to agreement, they have to learn to use the citizenship skills properly and to be mutually supportive. The hardest part of creating a functional society is working together in relative harmony to agree on what it will look like and do. That requires us all to overcome the problem of citizen apathy and citizen anger.
