If you look at the three methods that could be used:
(1) Constitutional Convention. I don’t think anyone from either party wants this to occur because there could be twenty-odd changes (term-limits, deletion of the Electoral College, removal of functions for the Senate, etc).
(2) Getting two-thirds of the House and Senate to pass? It’d be a end of career job for some GOP folks if they went this direction.
(3) State by state legislatures voting on a similar piece of legislature seems unlikely. You wouldn’t find any southern state agreeing to this.
So it’s simply a lot of talk without much to be accomplished. Now, I will say...if they ever get around to defining a militia within each state, and get the Supreme Court to allow a defined status...then you might see some creative measures to occur then. If you just said that no incarcerated or convicted members could be a member of a militia....it’d likely be waved as legit, and take the first step.
The author was headed in the right direction but is totally wrong on bump stocks being trivial. The definition of full auto is firing two or more shots with a single actuation of the trigger. Bump stocks only allow firing one shot per actuation of the trigger = not a machine gun. So banning bumpstocks is really a ban on the ability to pull the trigger quickly and MANY was to do this other than bump stocks. A nice adjustable trigger is a great aid to shooting fast so you can see where this will go if we lose this fight. Bump firing itself is easily done without a bump stock and infact has been done long before the bump stock was even invented. Allow a ban on bump stocks and we we be on a very rapid path to banning all semi autos.
