Nothing--no change to the Constitution without an appropriate amendment that goes through the amendment process outlined in Article 5 of the Constitution. When you talk about changes and what they should look like that is PRIMA FACIE evidence you approve of change (in some form). I do not, I will not, and I do not believe 3/4 of the state Legislatures would ratify any Constitutional amendment. Obama nor any other Democrat would put forth such a proposal if it had to go through the Ratification process. They would be made fools of.
