To be frank, there are people who vote in this country who have NO IDEA who the people are on the ballot, and that includes President and VP nominees.
They vote party lines. Always have, just like their parents taught them to. If they had to pick a name instead of their party affiliation, they would not know what to do with that ballot!
So, even if Hillary is forced to step down and do the "perp walk" or Trump gets bumped off, there are a great many who will vote a straight party ticket to prevent the other party from winning.
There are people voting in this election who cannot tell you who the current VP, Secretary of State and majority party leaders in Congress are. That's why asking for ID is considered disenfranchising those voters! They can't be expected to remember to bring their ID to the polling places.
