Apart from further Supreme Court nominations...the Trump Energy Policy is the biggest boost for the United States.
As a result the USA will come to dominate world wide coal, oil, natural gas and raw materials for the plastics industries.
That and the appointment of conservative lower court judges.
Of course, the ninth circuit will hold that anything Obama did cannot be changed.
Hopefully, the supreme court will correct that.
But the road to reversing Obama’s Kill the Coal Industry regulations will go through the Courts, and I bet more than one court enjoins Trump from repealing them.
