I imagine if Hillary were to actually die in October the Democrat states would pull out all the stops to change their laws and spend millions of dollars to change the ballots to put another Dhimmy’crat on the ballot.
One thing you can say for Dhimmy’crats is that they don’t let a little thing like the law get in the way of their having their way.
Well .. if only the Dems changed their ballots; you might end up with a “contested” election. That would not be good for anybody.
If you had people who voted for Hillary .. believing they would be electing the Dem candidate - whoever it was (and the Dems have some voters who might believe that), it would definitely be a “contested” election.
