I refuse electronic voting on principle
There isn't an argument for e-voting that holds up to scrutiny at the moment. None of the affirmations of companies pushing e-voting products are objectively substantiated.
* "[e-voting] could also potentially deliver significant cost savings" - how ? By magic ?
A national e-voting system is going to be bespoke because no two countries do it exactly the same way. That means that there is no product that can handle the specifics in an easy-to-understand, idiot-proof manner, which means that there is room for obscure configuration settings that can easily be set/removed to give some unknown advantage to the party that knows exactly how to (ab)use them.
And not to forget, not everyone has Internet access these days - so e-voting is not going to be a universal solution until Internet access is as basic as running water.
* “If we had it in place today, we’d already have certainty regarding the results of the federal election"
Oh really ? In France the vote is paper-based, and we only have to wait until 8 p.m. to get the metropolitan results. Overseas French territories give their results in the following 12 hours, by law. If your paper-based system does not do that, you might look into improving the system instead of replacing it with an untested/untrusted one.
* "on the issue of proof of identity"
Nice dig at ID cards, but please excuse me if I rofl. Proven ID on the Internet ? That won't happen without a serious overhaul of ID management in general. Whatever is chosen, the costs are going to be high and, again, each country is going to have its own specifications as to what is pertinent, so each implementation will have to take into account specific things that prevent one-solution-for-all and thus, no economies of scale.
* "votes can still be miscounted, misread, or even simply misplaced"
Nothing is perfect, but I have yet to see a democratic country with widespread voting corruption. There have obviously been instances, but we know about them because they were discovered, generally quickly discovered. E-voting opens the prospect of vote-rigging in such a way that it will remain undiscovered until a smarter genie finds out, or a disgruntled participant speaks up. That could take years, or more.
Sorry, but there isn't an ounce of worth to any of those arguments in favour of e-voting and there are currently iron-clad arguments against.
I've said it before and I'll repeat it as long as it takes : the only e-voting scheme worth it is the one where the specifications are open-source, the code is open-source, and everyone knows exactly what is happening and how.
Obscurity is not security.
