States will send delegates. These agents of the states will have commissions that delineate exactly what they are authorized to do.
For example, here is the summary of Florida's bill, HM609:
<>Article V Constitutional Convention: Establishes qualifications of delegates & alternate delegates to Article V constitutional convention; provides for appointment of delegates by Legislature; authorizes Legislature to recall delegate & fill vacancy; authorizes presiding officers to call special legislative session to carry out certain provisions relating to appointments; requires delegates to sign oath; provides for instructions to delegates; establishes circumstances under which convention vote is declared void; provides circumstances under which delegate's appointment is forfeited; establishes circumstances under which application to call Article V convention ceases to be continuing application & is deemed to have no effect; provides penalties; establishes delegate advisory group.<>
Most importantly our current demographics precludes a common core of values, historical views, culture and traditions. It was the Anglo Americans, that created our present Constitution. We Anglo Americans may end up slaves by the time the Third World delegates get done with a "convention."
It is not the time for a convention. A terrible war must come first and then victorious side will write "The Constitution."
