The important test will be the next Supreme Court justice Trump nominates. Republican presidents have followed a pattern of alternating conservative nominees with moderate/liberal ones, thus ensuring that justices like Scalia, Thomas, Rehnquist, etc., have never been able to become the majority. The Supreme Court hasn't reversed a single high-impact liberal decision in generations. If you look at American history, it's been pretty much a slow but sure march toward greater and greater centralized governmental powers and control.
