Many of these fellows have woke up and seen that this is the way it is and if they want to stay in the game they have to get on board, to mix metaphors a bit. Others have come to see that Trump is not the dunce they took him for and that his apparent lack of manners was/is necessary. While they maintain their reservations they will more and more applaud and support the results. At first, like Levin, they are positively enthusiastic about his appointments and the results of his rapid movement without mentioning the mover himself. The principled Constitutionalists have a hard time but even they are seeing that that time is past, that a Constitutionalist cannot get past the opposition because he has to defer to it and that the Constitution has been set aside by the Democrats and the Republicans and cannot be put back in place by purely Constitutional means. I have my own nits to pick with Trump but they are actually hopes that he will restructure the monster then return it to the Founders’ vision. I have my own ideas about that and they lean heavily toward the Article V Convention which Levin has done so much to promote. Congress cannot take back its ceded powers. Only the States, now, can put things right, if they will.
I believe it was Joe Sobran who wryly observed that we don’t let the Constitution get in the way of our national government.
He was a big advocate of Article 9 and 10, which have pretty much been dead letters probably beginning around Lincoln.
Any attempt to ‘get back to the Founders vision’ would run head on into the fact there are many interpretations of what the Founders meant. This was true almost immediately after the Constitution was ratified, witness the Hamiltonians vs the Jeffersonians. Or you could even start before ratification, with anti-Federalists like Patrick Henry and George Mason versus those who wanted a more powerful central government.
