Jonno, NO ONE is talking about a Constitutional Convention.
PLEASE try to get this and keep it in mind. Thsi is a convention, run by the States, for the purpose of proposing amendments to our existing Constitution, in accordance with the explicit provisions of Article V.
That’s ALL it si It is NOT a Constitutional Convention. Repeat NOT.
As a practical matter, though, the chance of that happening lies somewhere between the chance of you turning inside out and exploding, and that of civilization being destroyed by a Carrington Event.
Lots of things are theoretically possible. That something is possible doesn't mean it is worth worrying about.
