Nothing is going to be perfect, there’s always room for improvement, and there is a need for constant dilegence. That said, it’s more difficult than most any other times in our history, being that we are so starkly polarized. One perspectives opinion of what improvement is, not just being different from the others, but polar opposite, making compromise or bipartisan effort next to impossible. As a country we’re going to remedy that, or it will remain one of a thousand cuts that is to kill our country.
Keeping political views out of our court system requires extreme self discipline on the part off justices, all. You’re right that the SCOTUS is too political and thus, not unlike America generally, polarized and nearly split. It would really be far better for the country if presidents on both sides would nominate men and women that are in the middle, and maybe we could dispense with these awful 5/4 splits that are deciding everything. Personally I’d prefer non partisan moderate SCOTUS judges and a lot more 6/3, 7/2 and 8/1 decisions.
