Jefferson had the same concerns back in
1819. He went so far as to say that decisions that had given the court exclusive final say on constitutional interpretations, as well as political independence, had resulted in the leaven of the old mass
assimilat(ing) to itself the new and that things were regressing so badly that we find the judiciary, on every occasion, still driving us into consolidation or centralization.
If I understand, Jefferson was conerned about certain DECISIONS, as you say. Here we have a Supreme entering the public fray in free discourse, which is entirely outside the scope of her charter. To me, this does not bode well.
