Read Article V.
GoldenPup,
I have. Many times. What in particular would you like me to notice about it?
Congress can _propose_ Amendments by bicameral super majorities. But under no circumstance can they ratify an Amendment. - Only States can do this when they summon 3/4’s of their legislatures in favor of a proposed Amendment.
But States can propose Amendments too by Constitutional Convention. At such a Convention, the States must propose by summoning 2/3’s of their legislatures to be in favor of the proposal. But if you have 3/4’s ready to ratify, it obviously won’t be an obstacle to get 2/3’s to propose.
Is there something else to note?
