Article V of the U.S. Constitution states (my italics): “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…”
In his book The Liberty Amendments, Mark Levin gives a very in-depth look at the need for Article V Conventions, proposing amendments to:
establish term limits for members of Congress,
restore the senate (repealing the 17th amendment),
establish term limits for Supreme Court justices,
establish super-majority legislative override,
limit federal spending,
limit federal taxing,
limit the federal bureaucracy,
promote free enterprise,
protect private property,
grant the states authority to directly amend the constitution,
