little federal judge will stomp his feet and place on injunction on it. Then months of appeals and delays for new evidence by other side. Then months more to go on SCOTUS long range plans. Then SCOTUS on long vacation. Then a wimpy Roberts and Kavanaugh “well,sort of, I guess, but we don’t mean this is a a decision, we suppose....” answer.
If President Trump cites Amendment 14 Section 2 as the authority for his EO, then he can argue that a federal judge has no say because those courts are the creation of Congress and are inferior to the Constitution.
It would be different if Trump cited a federal law passed by Congress. That would put the lower courts on equal footing.
