I think it's time to encourage governors to tell SCOTUS to stuff it over this ruling, and go ahead with their state-level perogatives. SCOTUS only has power when its rulings are heeded, as Andrew Jackson once pointed out.
Everytime I use this argument to say that Bush could end abortion tomorrow if he wanted, I am flamed like there is no tomorrow. He has no duty to adhere to UNConstitutional rulings and could declare that life starts at conception and that unborn children have a right to life liberty ...shall I go on?
For the reason you mention, the SCOTUS ruling on executions could be ignored. WE are the government, not those black robed devilish globalists.
