I know, it's complicated. I found this conservative/libertarian guy tries to splain it, he's got most of the main points there except he left out what I think is the main one, the progenitor:

1) It's Jared's pet project. He's been working on it fuhever because his father went to prison. I think I read something somewhere he was politicking on it before he married Ivanka.

Then there's the other things the conservative writer mentions:

2) The please Der Fuhrer thing is quite operative here. The lemmings go with whatever Trump wants because he's got the base, even if it happens to be liberal..Jared convinced him it's the thing to do. This is something everyone on the left needs to keep in mind: Trump is not conservative, Trump is nuts. There are Trump's favorite narratives (i.e., "the wall") that have worked for him so long that he will never let go of them. But other times (i.e., DACA), gun regulations)  he has not figured it out his favorite narrative yet, so he flips and flops. With this one he has Jared harping on him, day in, day out. So it's become part of the narcissist's favorite narratives

3) Jared's harping was solidified when Kim Kardashian/Mrs. Kanye came for a little visit on related and in support. Bingo, light bulb: he sees how he can use it to counter the accusations of racism, likes to laud it with like the visit of the young black conservative business people group or whatever. And keep Jared happy at same time. A twofer!

4) the law, very conveniently at this time, keeps getting more stuff written into in it about sensible sentencing for white collar crime and corporate crime and lobbyist crime and election law crime as well as drug-related crime. A threefer, fourfer, fivefer....
