In a convention of the states works various amendments are debated, then, if selected, voted on by the convention, if passed then must be ratified by 3/4 (38)of the states legislative bodies or by 3/4 (38) individual state conventions.
The Constitution does not allow for any amendment that would eliminate the Constitution.
You want to talk about one thing.
Others want to talk about the Second Amendment.
Do I want the Second Amendment revisited, narrowly defined?
It’s still my take that opening up a Convention of the States opens the Constitution to whims we cannot control.
I don’t trust that process anymore than I trust Congress, the Senate, or the SCOTUS.
I didn’t suggest the Constitution could be done away with.
