Paper ballots were available; while the article doesn't say so, I assume few people used them and few people knew that- who wants to count paper, right? Well, when an election makes such little sense, everybody should.
When designing a system for electronic voting, one must make several assumptions:
- Machines are unreliable and will lose votes
- People are unreliable and will potentially lose data
- Machines are vulnerable to tampering and may be modified to lose or change votes
- People are malicious and will purposefully tamper with data
- Electronic voting machines are vulnerable to power failures, spikes, and similar supply attacks, some of those attacks could damage the machine and the data stored on it
Which is why I like the Open Voting Consortium, which has addressed many of those issues in a reasonably secure and verifiable fashion.
Until a solution similar to theirs becomes standard, every election is a stolen election, rigged through fraud.
