Buyer's Remorse: There Ought to be a Way to Shed the Candidate

   Trump appeal seems to be swelling, not diminishing. Still, it seems there should be a way to shed a candidate if you reach a point of buyer's remorse before the election.
  As in: No. We've changed our mind, We don't want this guy for our candidate.
   If a person is an office-holder, often there are ways of impeaching him. We need a way to impeach our candidates, as well.
   Now, since the primaries are being used to nominate the candidate, it makes sense to call an emergency election to renounce him as your candidate, all states voting the same day. Then, the question becomes one of mechanics: Do you have a vote of no confidence, first, with only your current nominee on the ballot, and follow a week later with all the candidates poured back onto the ballot?
   However you do it, I suppose I like the idea of being able to give your second thoughts a route of action. I like there being of standing him up, of leaving your fiance at the alter, so to speak. If you're shuttering at the thought of electing someone, if you can see it isn't going to be a good thing, if you fear the nation is going to crash if he is elected, you ought to be able to divert course and save the ship.
