Trump once tweeted indignation about a supposed bugging of the White House "by Obama", only to dismiss it as unimportant weeks later during an interview. That was a typical situation of his raising what would be important concerns, just to fail to given them the obvious significance later. His tales are to be taken as entertainment, not testimonials.
Still, at this moment it appears that he is sincerely interested in finding out who "Lodestar" might be. That he is taking the trouble to ask for that instead of dismissing it as "fake news" says something.
In some ways this Op-Ed seems like a natural extension of the recent situation with Omarosa, which lampshaded the kind of loyalties that Trump nurtures and earns. It is so toxic to even itself that defections and backstabbings are a necessary result.
And indeed, there is little to commend the author of the piece. He is by his own admission an irresponsible fanatic that happens to fall just short of letting Trump run unleashed. The one result that he seems to expect from releasing his piece is to make Trump's fall that much quicker and (from his point of view) less painful.
That strongly hints that whoever wrote the piece expects Trump to face rough water ahead, presumably at least in part due to the investigations against him. I assume that the hope is that the Conservative base will transfer its loyalties to the "Resistance" of opportunists who think nothing of supporting Trump in the open and undermining him cirurgically for optimal political results. That may well happen once it becomes undeniable that Trump is in league with Russia in a way that endangers the pride and safety of the USA.
It will not be that much of an improvement, and it may well not be an improvement at all, but it may well happen.
Of course, it would be incomparably better to have Trump supporters grow intellectual honesty and moral courage instead, but I can't think of any quick or painless way for that to happen. It certainly isn't likely to happen out of scandal alone.
