We should start by going one and one. One Senator for the State Government and one from the peeps of the State.
It’s the states that decide on Constitutional amendments.
The states can and should go for 100% state appointment.
“The Congress...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...as...the...Mode of Ratification...may be proposed by the Congress....”
We can get a convention in session and we can allow an indefinite amount of time for 38 states to ratify convention proposed amendments.
