I think they already have absentee voting going on in NC.

Replacing Hillary at this point will create a real mess... what happens to the votes already cast?
I'm not a constitutional scholar, but my understanding is that when you vote for a presidential candidate, you are really voting for an Elector pledged to that particular candidate.
If that's true, then replacing Hillary would not be a big deal. Electors pledged to Hillary would just vote for the current Dem nominee when the Electoral College meets.
If it looks like she’s going to be replaced, I will be requesting an absentee ballot and then file a federal lawsuit against the replacement.
I live in North Carolina.
I’ll win.
