Mark Levin is a fantastic Conservative. I have a few of his books.
I believe it is too late for the Article V solution to work. We are too far down the road to Fascism.
I think the only chance to restore our Republic is a response by the several States to a total economic collapse where in the Federal government becomes operationally insolvent.
The States will have to assert their Constitutional authority at such time and essentially dissolve ALL unconstitutional parts of the Federal Leviathan.
A true reset will require that ALL courts below the Supreme Court be dissolved, with the associated judges and staff fired.
Of course this can only happen in a movie script. The likely reality is that the U.S. over the coming decades will turn into a decaying third world Spanish speaking sewer.
You describe such a situation in your reply and if such a cataclysmic event occurs the Article V option will remain a very good vehicle for that reform. However, Nathan Bedford is also fond of reciting his own maxims and this one might well apply: the reform of failed socialism is invariably more socialism. So if a cataclysm occurs it will be a desperate fight in which both sides seek to reform the country in their own image. The liberals have never been known to let a good crisis go to waste and they will be very effective in describing their brand of tyranny as salvation.
We should be prepared.
