IMO this thing is a trojan horse to open a convention......we'd best FEAR this clause of article 5 of the Constitution:
"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,......."
once open, BEWARE - " valid to all Intents and Purposes "
I'd expect one of the first things they'd do would be to make the US, Canada, and Messico into one megastate.
