The flaw in that argument is that there have been 17 amendments besides the Bill of Rights already.
To have your perfect constitution back we would have to repeal all 17, which a COS could do.
No, no, no. It will not do anything to the Constitution. Only add amendments. The restrictions, limitations, and controls on the Article V process include all of the following,
acting in conjunction: The convention’s agenda is set by the 34 state applications (for the Convention of States Project, amendment proposals must “impose fiscal restraints on the federal government, limit the power and jurisdiction of the federal government, and limit the terms of office for its officials and for members of Congress”). Once 34 states apply for a convention on the same topic and the convention is called, state legislatures select and instruct their delegates;
At the convention, any single delegate can object to off-topic proposals as “out of order,” for which the objection must be sustained. At the convention, a majority of the states must vote in favor of any proposal in order for it to advance to the ratification stage;
Any delegate who proposes or votes in favor of an amendment beyond the scope of the agreed agenda OR beyond the scope of his/her state legislature’s instructions can be recalled by the state legislature and subjected to penalties according to state law;
Because delegates act as the agents of their state legislatures, a delegate’s vote that exceeds his/her instructions or authority is void. The courts could be called upon, if needed, to protect the process at any point (there are abundant precedents demonstrating that, in fact, the courts DO acknowledge and protect the historical Article V procedures) 38 states must ratify any proposed amendments for them to become effective. This means that it
only takes 13 states to block a bad proposal. Nothing wrong there. Right?
If, and that is a big if, their is a COS, rescinding the Seventeenth would be sufficient as a start. Frankly, we should have stopped at the Bill of Rights as you suggest.
