Moving beyond the immediate aftermath of the court decision, I really think we are screwed, as this article puts forth.
If partisan polarization continues to intensify, checks and balances will not save us.

The TLDR version is that our democracy to this point has been dependent on the party in power demonstrating restraint and not doing everything they are legally capable of doing. Now that norms are becoming worthless and the country is becoming, more polarized (wheras in the past violating norms may have hurt you electorally due to a more moderate electorate), as Schumer said, "everything is on the table". When you expect your oponents to show no restraint, you are forced to "lose" or abandon restraint as well.
Gingrich (and then Mcconnell) filibuster everything beyond what norms were. D's do away with filibuster for D's filibuster R judges, R do away with filibuster for judges, R's steal court seat by refusing to vote on D nominee then do the same, D's pack the court, add states, etc. The end result is our government loses legitimacy in everyone's eyes. It becomes a race to the bottom where we all lose. So sure, pack the court, add states, blame the republicans (and honestly they do deserve a disproportionate amount of blame in norms violation, though there is plenty to go around), but don't do it gleefully like I see online. This is not a good road to be on and we won't like the destination.
