You nutters wouldn't believe the truth, because you believe the Dems/Biden/whoever are as bad as Trump, and act in the same ridiculous ways. Not to mention the fact that one of the most moral and forthright men I've known - Merrick Garland - has been turned into a villain the eyes of the MAGAts. The reality is, this spectacle of the Epstein files wasn't acceptable among normal humans. The DOJ did their job independently of the Presidency (as much as possible), and didn't do so for attention or shock value. So, among normal humans, the Epstein files wouldn't be released.
BUT ... Trump swooped in and wanted to appease his crazy cult followers, so he put into motion the expectation that they would be released. So, he gave his critics ammunition. You said you'd release them .. so where are they? You convinced everyone there was something worthwhile to see in there ... and ... now there's nothing, and things are being held back. So you must be hiding something. You created this scenario where, on a good day, you're only bending the rules of the Constitution in the exercise of your powers. On a normal or bad day, it's much worse ... so, you're the Fuhrer, with nearly unlimited power ... show us the files.
As to the motivation ... you have to understand this is Trump. EVERYTHING he does starts with "how does this benefit me or make me look?" That's it. Nothing else matters until that is answered to his satisfaction. I know the MAGAt whackos think he's out to help them ... that's some of the dumbest stuff I've ever heard. Serious cultist wackiness. So, if the files were a big nothing burger, he'd release them. He'd make good on his "promise" to release the files to everyone's satisfaction, and he wouldn't look bad doing so, or otherwise be harmed. He'd do that in a second. But, if full release of the files would harm him ... he wouldn't do it. Whether that harm is direct (i.e. implicates him directly in unsavory and/or illegal activities) or indirect (would harm people he has an interest in protecting, because they benefit him in some way) ... that's the only thing that is really TBD at this point. But we know we have a lifelong sexual predator who is suppressing information he promised us relating to a sexual predator's exploits - a sexual predator whom he knew very well, and with whom he hung out with on a regular basis for quite some time, including the time when this sexual predator was active in his sexual abuses.
