Unless you’re one of those ornery folks who believe that only politically engaged Americans should vote, there aren’t many good reasons to oppose efforts to expand access to the ballot. Voter fraud is quite rare, and voting fraud — an organized effort to illegally disrupt elections — is hard to organize. So you might think that any restriction on the way someone can vote will unfairly marginalize potentially legitimate voters. That’s true, with one big exception: internet voting. No doubt — nationwide internet voting has an intuitive appeal. It would decrease the costs of elections. It would dramatically increase turn-out. It would allow marginalized communities to avoid harassment at polling sites. It would speed the vote count. A majority of voters regularly endorse the idea. There are two main reasons, though, why internet voting is, at best, a dream best realized 20 years in the future — if ever. The internet is not secure. It does not matter whether results are sent to an air-gapped system, because there’s plenty of technologies that jump air-gaps, and we know that big governments (like ours) use them to spy.
