I think it will be interesting to see how Trump's justices rule on this sort of thing; I suspect that they are not actually as beholden to him as people are inclined to think. They got into this to oppress minorities (they were pretty much chosen off a list of judges who were seen as reliable (in a Republican sense) on abortion and voting rights and so on), but potentially not to wholesale disassemble democracy in the US, and there's very little that Trump can do to them. I think he may find them less cooperative than he's hoping.
