Absolutely not.
It matters not who is in the gov/candidacies, it only matters to have stability and reliability.
If a president/incumbent dies the day prior to the election, so be it. That is not more important than the security and stability of the republic, including how institutions are handled.
BTW, that includes the absurdity of “early” voting, mail-in ballots, and of course “late” voting as is pushed by many. All these should be declared unconstitutional.
What section of the Constitution do they violate?
