The notion that Presidents should be able to ignore court rulings has been popular - very popular long before the 20th century had even started.
Certainly by the 1930s FDR was already happily rabble-rousing against the Court.
Wasn't it President Andrew Jackson who said of the Supreme Court; "they've made their decision, now let us see them enforce it." This regarding "the trail of tears," if I recall.
Yup. Lincoln ignored a number of Supreme Court rulings.
And got away with it.
All true, but has nothing to do with the current state of affairs where vast swaths of the population are expressing approval for the behavior.
It wasn't until LBJ that a vast swath of the population expressed an opinion about what POTUS was doing - and that swath was opposed to him. Reagan had a much smaller swath that supported him, but that was more agreeing with his philosophy than active support of his political acts.
Now we have a significant plurality that does not care that POTUS's actions are unconstitutional, illegal, and/or fattening. In fact, they see sidestepping all of those bothersome and icky procedural and legal issues as A Good Thing
TM. Seems to me that about 1/3 of those in the plurality are from the "He's one of us racially" camp and the other 2/3 are from the "He's a liberal like us" camp. In either case "their side" finally gets to be winners.
stay safe.
