Republicans will have only themselves to blame. They were the ones who let Think Tank intellectuals pack the courts with ideological zealots. Thus

Therefore, the conservative majority and its extreme positions will destroy the U.S. Supreme Court as we know it.

Hence, I expect we will see Chief Justice Roberts presiding over a very different Supreme Court in eight or 10 years. The composition of that court is unclear but I suspect Conservatives will not like it. On the other hand, Erwin Chemerinsky will like that court.
