The actual election is the Electoral College. We have had one candidate die before they voted and they still voted for president. It would be the right thing to do to have a new election, but that is not the Constitutional option. That remedy is for the EC/Congress to fix it before January 20 and succession to fix it after.
Yes, dying and fraud are two different things.
“We have had one candidate die before they voted and they still voted for president.”
How did they vote? Veep of same party, other?
