Are you arguing the Electors become disqualified? That may be true with a certain state but it is difficult to believe a state would hamstring itself in such as fashion given a last minute replacement.
Which goes to my point, if Biden is replaced one way or the other prior to the election, or even shortly thereafter, given the impossibility of performance those Electors are relieved of that pledge.
We may continue to disagree, but you can have the last word.
No I am not talking about the electors. I am talking about the early votes . The voters choose which slate of electors vote. Early voters voted for Biden and his electors but the name on the ballot was Biden. If he is replaced with Clinton while the elector slate is the same the name on the ballot is now Clinton. The early votes for Biden cannot be merged with later votes for Clinton. It cannot be presumed that a Biden voter would automatically be a Clinton voter. So the early Biden votes would be discarded. Enough discarded votes Trump wins the state and his slate of electors votes
