SCOTUS bears a tremendous amount of responsibility for Trump's power grab. Its immunity-granting ruling means that it's extremely difficult to stop a President who decides to simply ignore the law. Even if you think Trump is a "good guy" who is "doing the right thing" , he's setting precedents whereby a President who is a "bad guy" could turn dictator, and then what? Literally the only option is impeachment, but the…
1. While in office, relying on the DoJ's policy of never indicting a sitting president. (Not to mention the fact that they control the DoJ.)
2. On the last day of their presidency, they resign. The VP is sworn in as president, and pardons the now-former president for whatever they've done. (The former president can of course, before resigning, pardon the VP for anything they might have been involved in as well.)
Easy peasy.
