The problem is, this isn't just about politics. It actually will have an effect on people's lives. Putting judges in the highest office, for life, who have views that are detrimental to large swaths of the population in terms of personal freedoms goes beyond politics. I don't love the nuclear option for circuit court justices... but at least with the circuit court judges being basically political appointees, you still had some semblance of a fair and balanced court to appeal to when the SC was more fairly split. It gave people wanting a federal appeal a pretty fair shake. Now it's unbalanced. That's why I would support the court going to a number that puts the balance of conservatives and liberals (or whatever the judicial equivalent is) closer to 50-50. I'm not advocating putting 50 liberal judges on the court to drown out the conservatives.
I recognize that this would be a precarious position for the country, but packing the court to one side via scheming and deceit is also a precarious position for the country. McConnell already effectively packed the court from the Republican side with his antics by allowing his party an opportunity to make at least one pick they never should have been able to. I just want the scales of justice to be more balanced and not let a guy like Trump or McConnell put their finger on the scales.
