The issue is a Constitutional Convention, with the expressed intent being to return the United States to its Constitutional Roots.
Ahem. It is an Amending Convention authorized under the existing Constitution. It is no less and no more than any other Constitutional body.
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; provided that no amendment which may be made prior to the year one thousand eight hundred and eight shall in any manner affect the first and fourth clauses in the ninth section of the first article; and that no state, without its consent, shall be deprived of its equal suffrage in the Senate.
Really, how tough can it be?
Things like this are sold to those who are looking for the magic bullet to fix their ills, by those who know they will direct it to achieve their aims.
We have a perfectly good Constitution. Let's use it for a change.
