I readily acknowledge that there have been well over 400 State applications for an Article V COS in our history. Yet as you note, Congress has not yet called such a convention. And from this obvious fact, you draw the conclusion: There's "not a chance" that Congress would ever do so.
I have difficulty following your reasoning which only makes sense if one thinks that the simple arithmetical number of applications is in itself decisive for the purpose of a Congressional Call, and not the substance of such Applications.
Though it's not spelled out in Article V directly, there is a very long tradition, completely backed up by Article V, that State Applications must bear on some more-or-less same idea that could inspire 34 states to work together in the proposal of amendments to the federal constitution. This is where your hated "aggregation rule" comes into effect.
As you well know, Article V gives equal dignity and power to two modes of proposing amendments to the Constitution. One mode is by the Congress itself; the other is by the States themselves, acting in concert at least to the point of showing a 34-State quorum on common areas of concern. This is what the principle of aggregation refers to.
When Congress takes up a proposed amendment, that body is already "aggregated" as to the purpose of doing that. To get two-thirds majorities in both houses, both must then "aggregate" their approval. Then they send their product to the States for the necessary three-fourths-of-the-states ratification before it can become constitutional law.
My point is, when Congress uses its Fifth Amendment powers, it is doing so as a more-or-less unified body as to the issue under dispute. And two-thirds of both chambers must agree, before the matter can be sent to the States for ratification.
So why should the States have to show anything less than indications of common, unified, purposeful action, when they submit Applications for an Article V COS?
For the record, of all the 400+ State Applications thus far, only four have applied for "a general convention." But I think if another 30 States were similarly to apply, Congress would have no choice but to issue its constitutional Call.
But probably few States are all that interested in convening a "general convention"....
On the other hand, we have States vitally interested in sending a Balanced Budget Amendment to the Constitution out for State ratification. Their number has most recently been "aggregated" at 28. That leaves another 6 states to go, before Congress is impelled to issue its CALL.
I really don't understand, Jacquerie, why you find anything "unfair" in any of this. We have Article V, we have history, we have precedent, to go by.
I just hope, and encourage you, not to lose heart, not to lose morale over this. Congress does not sit as critics of Applications, or judges of their content or merit. I gather it might feel that it has no obligation to act at all, unless and until 34 States Applications aggregatable as to general subject matter have piled up on the desk of the Clerk of the House....
