I don't know why everyone circle jerks over SCOTUS so much. Sure, if RBG, Kennedy and Breyer are replaced by Trump, the 2016 election will have been very damaging long-term, but Gorsuch replacing Scalia just maintains the status quo. And it's not like the Republican Justices besides Gorsuch are spring chickens either.
Yup. Kennedy retiring would have been devastating...but he didn't, and it's not clear that he will during Trump's tenure. It's not yet clear just how important the 2016 election was for the Supreme Court.
