The system used 200 years ago? Before parties existed? Come on H2O, surely you have a better argument than that. The Right to Assemble may have some repercussions that people didn't expect. Just as the right to free speech sometimes gets annoying. Or the right of the people to own and bear arms seems to be in the way of the agenda of others. It doesn't change the reality of the situation. And the SCOTUS refused to hear the arguments after this was decided by the courts, upholding the decision.
The reality is, as the parties in those states decide to sue for their right, the states will change that policy. Look into it, H2O, you will find that I was not "ignorant" after all. Look at the states that have changed to a closed system, find out why it happened.
