It's going to take reversing about seventy-five years of constitutional breach to do that. Will take at least sixteen years straight of steady no-nonsense conservative POTUS at the helm and hope for the best in Congress.
With sixteen years of true "I get it" conservatives as POTUS (Palin and the her 2016 true conservative VP to be elected in 2020) we would stand a good chance of getting a conservative majority in SCOTUS with the goal of reversing previous unconstitutional decisions like Roe v. Wade and using the Commerce Clause to regulate anything that moves.
The core of the problem is that the foundational check on the powers of the Federal Government in our system is, or at least was, the Sovereignty of the States in domestic affairs. The Constitutional separation of powers between the departments of the Federal Government were never intended to restrict its powers in the absence of pre-eminent States. And, naturally they do not accomplish this goal.
So rally around the latest national party offering. Get out the vote for the "real conservative" inthe race. But don't expect anything to change until a majority of the voting citizens again understand how the system was constructed.
