Convention of States
I first heard of this idea from Mark Levin and have been following closely. I do not hold up much hope for being successful in my blue, blue state, but would love input from anyone on the ground and also opinions from anyone else who is interested in this movement.
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."
It does not require all states to call for the Convention, only 2/3. It does require 3/4 to pass the amendment. the founding fathers didn't want it too easy to modify the Constitution.
