What Article V Really Says
“The Congress, whenever two thirds of both Houses shall deem it necessary, shall propose Amendments to this Constitution, or, on the Application of the Legislatures of two thirds of the several States, shall call a Convention for proposing Amendments, which, in either Case, shall be valid to all Intents and Purposes, as Part of this Constitution, when ratified by the Legislatures of three fourths of the several States, or by Conventions in three fourths thereof, as the one or the other Mode of Ratification may be proposed by the Congress…” [boldface mine]
Note that Congress “calls” the Convention. The States don’t “call” it – all they can do is apply to Congress for Congress to call it.<<<
This is one point right here that the author gets wrong. Mark has stated this exactly as the author uses to say mark is wrong. If the author is arguing the same point as Mark has stated then it is obvious to the casual observer that the author does not understand what Mark is saying.
The notion of the runaway convention. Each state appoints its delegates and can fire them if dissatisfied with what they are doing. A supermajority of the legislatures of the several states must approve (ratify) any proposed amendments. That is a very difficult process and many amendments have failed to reach the standard.
Si!
