In the novel I never finished from 10 years ago (darn it), I had a Hillary character blackmail the VP nominee a few weeks before the election and take his place. She became VP and you can guess what happened next.
well the creepiest part of this whole campaign was when there was this rumor that Biden would drop out of the race due to health reasons on oct 5 and on oct 5, he actually stopped his campaign for a few days because his mother in law passed away.
