The Supreme Court is 6-3 or at worst 5-4 conservative though and in the end they all bow down to them when it comes to the law. Every President gets to appoint endless piles of judges as openings come up so while there’s 3 years’ worth of Biden judges, there’s also 4 years’ worth of Trump judges. 8 years’ each of Obama and Bush judges, etc etc. It’s just a part of things, but SCOTUS appointments last longer and are the most important. If any Biden judges make fuckups massive enough to make a difference, the appeal will wind toward the conservative SCOTUS.
