There is exactly one path to solving this problem, and it's going to take a lot of luck.
Vote Blue no matter who, even if you have to hold your nose while doing it. Yes, there are numerous problems with Biden, but there are exactly zero situations where Trump would be a better option. It sucks having to choose between the lesser of two evils, but better to choose the lesser evil than have the greater evil forced upon you.
Hope that both Thomas and Alito either retire (hahahahahahah, never gonna happen, I know) or die during Biden's term, giving the SC a 5-4 liberal majority.
Push through a Supreme Court challenge against some of these draconian anti-abortion laws and have women's reproductive rights restored to at least what we had with Roe v. Wade, if not more.
Enshrine abortion rights into law. A constitutional amendment would be best, but there's zero chance of that happening, but laws should be put into place ensuring that what happened two years ago doesn't happen again.
The president does not have authority to just add more judges. The size of the court is set by federal law and requires an act of Congress to change it.
people blindly believe we have to live constrained to what these two parties are bought to sell us indefinitely
Because like it or not, we do. At least for the time being. There are no viable third parties. I know it sucks to hear, but it's the reality of the world we live in. Don't get me wrong. You're free to vote third party for whatever reasons you see fit, or no reason at all. But if you do, just don't complain when you're watching the inauguration of President Trump on January 20th.
