There is no known reason to believe this, but conspiracy theorists don’t traffic in facts, so assume for purposes of argument that Trump’s name shows up on an Epstein client list. Would MAGA care?
You can divide the MAGA movement into extremists who believe that Trump was sent by God to expose the corruption of the left-leaning elite and more mainstream types who follow him in spite of his personal shortcomings because they hate the same people he does. The latter group is perfectly aware of Trump’s record and simply does not care as long as he delivers the goods for them. Hypothetical facts establishing a closer tie between Trump and Epstein would make no difference whatsoever to them. As for the extremists, they would find this information uncomfortable, but they would find a way to spin it that would preserve the narrative. For example, they could say that Trump was only trying to get close to Epstein in order to expose him and his coastal elite henchmen at a later date.
In short, the answer to the question is yes–we have reached peak Epstein, barring some new incredible public relations blunder by Trump or his underlings.
