Well, states and municipalities could decide to observe the Constitution and preemptively fix their laws; 4 Chicago suburbs with total handgun bans including the notorious leader Morton Grove were defendants in the original lawsuits and 3 gave up rather than fight.
And who knows, the really bad states are also in the worst financial shape by and large (strange, that...), they're going to be under new management sooner or later (already are in NJ, the other big ones would be NY, MA, IL and CA).
