The best explanation I’ve seen is that this was a calculated pick to distract and lower the bar for Trump’s eventual real nominee (Paxton?), allowing the Senate and public to swallow someone who will still enable the DOJ as Trump’s own personal vengeance law firm. It is also again Trump nonsense taking up all the oxygen, preventing debate over his other extremely problematic picks like Tulsi Gabbard.
It gave Gaetz cover to resign and prevent his ethics probe from being public, and if this theory is correct, he’ll withdraw from consideration before any of that information is made public. Mission(s) accomplished.
Yeah, I mean, obviously this is not a 4D-chess move. Trump acts instinctively but he’s had a lifetime of narcissistic manipulation informing that instinct. Gaetz would already have been looking for ways to maximize his visibility while skirting the investigation, Stephen Miller probably could have contributed the “trigger the libs and deep state at first, and make it seems like they get a win once they’ve got it out of their system” part.
Everyone around Trump is self-interested evil in their own way and I could see how it works together pretty well.
