So I'm a fervent reader of every supreme court case that comes out, its like patch notes for America. I knew this was coming but nobody knew it was coming before the election. This is perhaps the worst outcome for the country as a whole to go into such a contentious election that WILL see some kind of legal action against it with a divided court. Especially since it doesn't actually affect anything but perception; I have NO DOUBT Trump is going to win and even if he didn't he has until late January to appoint the next SCOTUS judge, and he will. So the only impact of her dying before the election is increased anger, aggression, and conspiracy theories. Instability for no reason.
I did not like RBG. I'm not glad she's dead as i had no knowledge of her as a person and no personal animosity to her. I just disliked the way her juris prudence was based purely on emotion and ideology and never the law. So I am glad we will get a better judge on SCOTUS but in reality not much will change.
I'm certain the next justice will be more right wing but SCOTUS picks are not really left or right, once you don't have to answer to anyone you stop being in a political party (which is why we appoint justices for life). For example since getting on the court justice Kavanaugh has sided with RBG more often than the conservative wing of the court. So all the people yelling "this is the end gay people and any women who need an abortion will end up in a camp" are being dramatic. There will not be any large scale fundamental changes.
