No doubt the forces arrayed against decentralization will be immense. There's certainly no guarantee of anything. K-Street will fight tooth and nail to avoid the expense of lobbying fifty state legislatures. I also suspect the uniparty will maneuver behind the scenes to convince/bribe key state legislators to veto a convention.
As for the Left, they've convinced a nation once dedicated to liberty that the end purpose of government is democracy. When the media realize this Article V movement is real, perhaps we'll have a debate over first principles.
