I think that he Epstein stuff is because in the capturing of MAGAs, that starts with small conspiracy theories- chem trails, royals are lizards,the elite are lying to you, vaccinations will kill you, 5g waves will make you sterile, the Clintons eat babies and worship the devil,- they throw in some particularly disturbing ideas, the sex trafficking scandals are a part of it, along with the Epstein files.
Those people who have been drawn in, have been led to believe that Trump will fix it all. He will get out the bad people establishments and make everything right again.
Him not only refusing to release these files, but potentially being in them, is a huge dose of reality that hits like a wave. If he's lied about this, his biggest promise, the lynchpin that it all revolves around,what else might not be true?
