The congress doesn’t get to call the convention. Only the states can do that. Ratification of proposed amendments...that is problematic. But we will see. I plan to propose amendments that will neuter the feral government. And restore federalism.
The whole scheme assumes conservatives will control the agenda and the socialists and RINOs will do nothing. Best case — conservatives get more of their agenda enacted via Constitution that is subsequently ignored by the socialists and RINOs that run the country. Worst case - socialists and RINOs find a way to get more of their agenda passed which conservatives will dutifully obey.
The root problem is that conservatives need more votes and more power. I don’t see conservatives ramming through their agenda. No magic bullet here and lots of downside possibilities.
