Trump is a whole lot smarter than people generally give him credit for, maybe not in an intellectual, book-learning sense, but he "gets" people and knows how to get what he wants out of them. There are touches of Fidel Castro and even Charles Manson (yes, that's what I said, Charles Manson) in his people-skills kit. All Fidel had to do, was to pout to the rest of the world, that doesn't like America in the first place ("hate us because they ain't us"?) how mean the United States was to him, with that mean old embargo of theirs, and he has the world eating out of the palm of his hands. And say what you will about Manson, anyone who could get his followers to do all the things they did, in uncritical allegiance to his person, has got some mad people skills. Think of the three young ingenues jauntily walking to the courtroom with beatific smiles on their faces, because they were doing it all for Charlie. Happy as little larks. What a spell he held over them!
Trump is feinting into a "not pro-life but not pro-choice either" message to try and snag people who are kinda-sorta pro-choice, but who aren't terribly enthusiastic about voting for Biden, trying to assure him that they have nothing to fear from him. And in a deft bit of triangulation, after a fashion, he can look to pro-life people and say "what are you going to do, stand by and watch Biden get re-elected, or will you vote for me instead?". IOW, "I'm the best you're going to be able to do, so just deal with it".
I don't think that this kind of thing comes from his own mind. There's somebody from that special race that gives him this kind of direction.
Even if the thinks that he had this ingenious idea, there's probably somebody making him "wise suggestions".
