on social issues, the SCOTUS has been a lagging indicator for a good reason: it has always sought to preserve its own legitimacy. roberts get this very acutely.
so it has never really been on the vanguard of deciding any social issue--it rules to catch up with society. this is a huge departure due to the deliberate placement of judges who are outside the mainstream of america and inside the mainstream of only the federalist society. that approach is now bearing fruit (or rotten fruit, depending on your outlook).
so a few things are going to happen:
1. the SCOTUS will have made the charade public for even the most ardent apologists
2. its authority in non-commercial cases will be permanently jeopardized (a very good thing for both sides of the aisle)
3. the judges who did this will be de-legitimized and yes, i believe that legislation to end lifetime appts might be in the offing.
