A serious question:
In the presidential election contest, why will this matter?
If ol' joe's name is on the ballot, even after he's been replaced by, say, Josh Shapiro... so what?
When you cast your vote "for president", you are not voting [directly] for the candidate himself.
Instead, you're voting for ELECTORS who will in turn [be presumed to] vote for that candidate when the Electoral College convenes AFTER the election.
In an extraordinary set of circumstances, I believe the electors are not "bound" to vote for ol' joe and ol' joe ONLY. They can cast their votes as they see fit.
(hence, the "faithless elector" instances of past years)
So... those who wished to vote dem-communist could vote for the "Electors for joe biden" knowing that those electors would in turn cast their votes for the ACTUAL presidential candidate of The Party.
I seriously doubt any blue (or even purple) states would try to block such a switch in voting.
I will state this again:
All this "news noise" you hear and read about deadlines that make it too late to "change names" on the ballot is nothing more than FUD -- distortion to confuse you. Ignore it.
I invite rebuttals to this post.
Anyone?
