As the previous commenter said, Roberts has demonstrated many times that he cares about the fact that this court will go down in history as the Roberts court, and that it will forever be remembered for Dobbs. He has attempted over and over again to earn back that status of legitimacy, from issuing the first ever code of ethics to rejecting a challenge to the ban on gay conversion therapy.
I do not like SCOTUS at all, I think they’re a bunch of lying motherfuckers right now, but I also think Roberts recognizes the court is still on razor thin ice with the public because of Dobbs. I think they will not save Trump, especially since Trump has nothing to offer them in exchange.
