I don't think he had any idea they were going to raid him and no idea that they would manufacture charges against him.
These people are evil and depraved beyond anything we've ever had in America. I can't think of an historical example of one political party in America trying to put the other party leader in jail. Democrats literally want to eliminate the "Trump" Republicans so that America can be a glorious one party state.
Hypothetical;
Let's say he did/does have copies of everything. This isn't hypothetical; He's been hounded since before he even took office and he's been hounded ever since. I tend to think that only a complete imbecile (in Trumps position, not referring to you or anyone else) would
not think he'd be once again set up for a fall, in any manner possible.
So, the doj and fib find a greasy judge to sign off on the warrant and the fib goes door kicking at MaL. They take as many documents as they can, "un-classified" or otherwise. Then, they redact the affidavit in almost it's entirety. And actually, I don't think they "found" a greasy judge. Rather, I think they've all been cozy for quite some time.
Back to the hypothetical; In latter October of the 2022 mid-terms, he releases everything (that he's retained copies of, which should be "everything") to the general public and says "here, you make up your own mind and vote accordingly". He knows the msm will just bury it, so no sense wasting any time on them. The general public is accordingly incensed and there is indeed a Red Wave/Landslide. The same concept is appropriate for the 2024 Presidential election, if he chooses to wait that long.
In so doing, he's burned down the fib, doj, the msm and the dims. He's trapped them in a similar manner as to what Musk has done to twitter.
Now, one could argue that the hardcore "never Trumpers" will never change their minds (because of the release of documents). To that, I would agree. However, they are not the target audience. The target audience is the moderate, more "middle of the roaders" that definitely have the ability to sway elections.
I dunno, we'll have to wait and see. What I've said above seems altruistic, even to me. I remain optimistic and still hold hope of seeing justice served to the nefarious agents of darkness that are working to destroy not only Trump, but our Country as well.
