The proposed amendment does nothing whatsoever to change, alter, or revise any aspect of the process of Amending the COnstitution. This ONLY has to do with repeal of legislation or regulation. To repeat, ONLY legislation or regulation. NOT the Constitution.
In my opinion, all this would be made unnecessary if the 17th Amendment were repealed so that the Senate could fulfill its intended purpose as the voice of the respective States in the Federal legislative process.
At a threshhold LOWER than that of amending the Constitution.
How about we instead work on getting the 10th elevated back to its proper place? We already have checks and balances on federal power - that are ignored - the solution IMO is not to create another check that will be ignored, but to get the existing checks and balances restored.
