One of the things we need to do is to removed corrupt leftist judges from the courts (including the SCOTUS).
True but that takes a supermajority of the senate to impeach judges which we aren't likely to have for some time. Or it takes a conservative President which we don't have. And at the state level it requires conservative state governors and state congressmen and voters. And even if you do that, they still aren't going to be very willing to interfere with elections. Especially not when election officers are saying everything is fine.
Trump made a lot of progress on the judiciary. But progress is now in reverse. And the more immediate solution is better election laws now. We have a better likelihood of passing better election laws that make it harder to cheat and easier to catch cheaters than cleansing the judiciary.
