Paper ballots are pretty trivial to cheat too, you’re dependent on the honesty of party officials and poll watchers.
After a vote we get to watch the news go from counting station to station to announce the results.
There are usually a few recounts etc but it rarely takes longer than a day or two and tbh which is more important done right or fast?
If you live in a place like I do, we’re a one party place where primary elections are the real elections, and you don’t have the competitive pressures that are inherent to a multi-party contest.
We also had a huge upsurge in “write in” votes, as the paper forms are difficult to interpret.
