Why? Kindly tell how that would happen.
The Constitution is currently the law of the land, so it governs (and restricts certain actions) according to what it says. But, when you have a “Constitutional Convention”, it’s changing the document that governs what we do.
You don’t have delegates limited by a “Constitution” that they are there to change in the first place, doncha know...:-)
Those delegates are “at the top of the heap” at that point.
