What makes anyone think that even if you pass new constitutional amendment that the federal government would obey them?
The only solution I can think of is nullification. The states created the federal government therefore the states have the ultimate authority for determining whether federal laws are constitutional.
If two people have a contract it is unreasonable to assume that only one of the people in the contract has the sole authority to interpret the contract.
I am not going to poo poo this effort but I do not think just because there is a new amendment that it will change the current relationship of federal government to the states or its people.
I will absolutely support Mark.
