I think the answer is to have some kind of rule of succession which allows
things to go on as usual. A vote for John Smith is a vote for John Smith or
his delegated successor.

I agree for legislative body candidates or members (since the voters would
expect that a successor will follow the person's legislative policies- i.e.
the party's platform). However, there are major elements of discretion/
personality/ knowledge for executive and judicial offices involved such that a
legislative body can/should fill any such vacancies as a default remedy.
I mention again having YES/NO votes for such offices also as a safety measure
if a popular incumbent dies just before an election so that the voters can
vote NO on obviously unqualified candidates for such offices (especially
candidates who kill other candidates).
