If Congress has become “dysfunctional,” as you put it, isn’t it even more important for the executive branch to be highly responsive to elections? Otherwise you’re positing a system where all the governance is performed by a civil service comprised 90% of laptop class democrats, with elected Congress merely laying out procedural rules for how policy should be adopted and the elected president merely supervising compliance with those rules. I can see why democrats love this idea, but I can’t imagine why you’d think it would be a persuasive argument to anyone else.
Speaking of “lawless”—if legal conservatives stooped to finding constitutional principles in “emanations from penumbras” we’d have a heck of a lot more fun. Why not have a “living constitution” that reflects our view of what modern developments demand?
