I don’t think you ever want to have a Constitutional Convention. God knows what’s lurking in the sidelines.
STRICT PARAMETERS set before proceeding. Secure the ballot box. Otherwise NO GO.
That’s how we wound up with the Constitution to start with. They assembled to revise the Articles of Confederation....and no more.
An Article V State convention is just a way bypassing Congress to get amendments to the states for ratification.
3/4s of the states are not going to remove the Bill of Rights & 3/4s of the states are highly highly highly unlikely to pass anything dangerous. They are also unlikely to pass anything useful. Still its worth trying.
