Question:

In regards to the number of delegates that would come from the «several states» at an Article V Constitutional Convention (that hasn't happened since our Constitution was created), is there a formula or protocol that dictates that the voting strength between states would be of equal number, or would the number of delegates be proportional to the state's respective population? - Don

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; - US Constitution, Article V.

The Constitution does not specify how the states are to ratify the proposed amendments beyond giving the options of either by the state's legislature or by convention. Congress may set that the ratification process shall be by legislature or convention. How the delegates are selected or the number is totally up to each state.

The number of state convention delegates does not matter as to the proposed amendment becoming added to the Constitution. Each state only has one vote.

A primary object of such a national institution should be the education of our youth in the science of government. In a republic what species of knowledge can be equally important and what duty more pressing on its legislature than to patronize a plan for communicating it to those who are to be the future guardians of the liberties of the country? - Eighth Annual Message of George Washington, December 7, 1796
