I don't think you quite grasp how it works. For any president to nominate a Supreme Court Justice, there has to be a vacancy. In 2016, Justice Scalia died in February, nine months before the presidential election. Senate Leader Mitch McConnell refused to hold a confirmation hearing for president Obama's nomination to replace Scalia, saying it was too close to the election. When Justice Ruth Bader Ginsburg died in September 2020, two months before the election, Turtleneck rushed through the confirmation of Trump's third SCOTUS nomination. That's how it works, and there's nothing that can be done about it. You can now look forward to same-sex marriage, civil rights, race laws and who knows what else coming under attack.
