Roberts is bad. I doubt he will rule for Trump. It doesn’t take 5 justices to issue a stay like this.
Roberts tends to save his back stabbing for the big cases. This isn’t one. My guess he will side with POTUS here. Probably because the GOPe doesn’t want this precedent either.
They want the names of everybody he has done business with or made donations to in order to dox them and make their lives miserable or put them out of business altogether. That’s what/who he’s protecting.
