What is the process for vacating an election? We don't reside in a parliamentary system. The constitution provides for impeachment and 25th amendmenting a president as the 2 ways of removing him. If we somehow successfully achieve either of those 2 things (which I seriously doubt), we end up with Pence. Pence would normalize our relations with our traditional allies and repeal Trump's tariffs, but his judicial appointments would be the same. Not sure if the 4 year terms are constitutional or if they're established by some other law enacted by congress. But I don't know of any legal means of vacating an election.
And it's not like our elections have been free of shenanigans in the past. I'd assert that the majority in Bush v. Gore erroneously took from the FL supreme court the final authority of FL law. Back in 1960, there is a good chance Momo rigged the Cook County vote totals (similarly to what happened in that 1 NC district this year), and that put Kennedy over the top. (Why Kennedy then appointed his brother as AG and went after the mob is a mystery, and it wasn't good for his health, but that's another matter.) Going further back, there was the 1876 deal handing the election to Hayes and the 1824 alleged corrupt bargain where Clay gave his votes to Adams so that the vile Jackson wouldn't win. And before that, Burr tried to steal the 1800 election from his running mate, which brought about the necessity for the 12th amendment.
Don't get me wrong. I alternate between angry, sad and numb. But the only thing we can do about it is impeach Trump, 25th amendment him or vote him out of office (and prosecute all those members of his team who committed crimes).
Blah blah blah, Trump and his whole administration should resign, including Pence, and any laws and rules passed under his admin should be repealed, and all judges and justices should step down for sake of the integrity of our democracy. I’m not suggesting any of this will happen, but it should.
