I work in games.
The programming on games is generally not the most secure thing largely because of time and expense...more focus is put to gameplay systems than backend stuff. And we're not talking about whether it can be cracked - of course it can - computers do that kind of thing really well. My argument is doing it without a trace that it has occurred is a totally different beast, and not just something you can easily spin up.
I would hope that voting machines are not connected to any network, honestly...maybe they are though...that would be troubling, but with proper security, logging, and monitoring I'm still having trouble with the idea of 'no one would ever see it'.
