This is a bit of a tangent but I think reports like these strengthen the argument against electronic voting. There's basically no way of building a secure electronic voting system that can beat the security and auditability properties of old school pen and paper voting.
There’s actually a pretty interesting approach in which: voters can see that their vote counted, everyone can tally anonymous votes, and it is resistant to DoS https://people.csail.mit.edu/rivest/pubs/RR14b.pdf Of course, the real problem would be explaining to the general population that this works. Great in theory, but will never pan out
Show me your receipt saying you voted for Big Ron and I’ll give you a fiver and/or won’t hit you in the knees with a spanner.
