When there are multiple simultaneous elections happening in the UK you get multiple ballot papers - one per race. You then put them into separate ballot boxes. This obviously doesn't scale elegantly to the kind of ballots that go from President to dog-catcher, but you could certainly separate them into pink, blue, yellow, and white ballots and count in parallel.

Well.. yes it is indeed technically possible to count a large number of paper sheets by hand.

You don't have to use the same system for the higher risk ballots.

A foreign state isn't going to spend millions trying to subvert the vote for the head of "Wyoming School Board 45".

When I was at university our student elections were done on computer. 20 years ago. Nobody really cared about them, it was perfectly reasonable, you'd only have to bribe/threaten 3 people to make the result whatever you wanted.

If you put the national election in the hands of 3 people though, then you have a major problem.
