“Congress has nothing to do with a COS other than the date and location of the convention. That’s it.”
I would say that is a rather naive view.
You won’t find date and location in the Constitution.
So the Congress IMHO can inject itself in any number of ways based on rules as can the States themselves, which is why the Assembly of State Legislatures is attempting to set some rules that will guide them.
What the Congress does or doesn’t do is a another subject entirely.
In addition you are making an assumption that what I am telling you is actually how I believe. I am telling you how one side of the issue is likely to respond to a convention call or a move to request a call. I am listening to both sides of the issue with good points made and wisdom on display. The red state blue state issue alone should cause anyone wanting an Article V to pause and examine the possibility of unintended consequences.
Unfortunately, the consequences of doing nothing are intentional and predictable.
