For a little bit of context, from what I recall, the real push towards electronic voting in the United States came after the 2000 presidential election and the controversies that happened with paper ballots and the tight recount in Florida (eg "hanging chads").

Paper isn't perfect and I think the thought at the time was pushing elimination of all of paper's errors. That being said, digital voting of course has far worse problems if you don't do it right (and it's pretty clear it hasn't been done very well in the US). In hindsight, that was a poor push. I imagine it's actually possible to design a digital voting system that is fairly secure (eg air-gapped voting machines, secure data storage and transmission, integrity verification, redundant security features, thoroughly tested, and -- most critical of all -- paper backups), but it would be very difficult compared to designing a better paper ballot system, and probably quite a bit more expensive.
