I agree with your sentiment, nevertheless every time I've used an electronic voting machine I've found it very clunky and difficult to operate. It's kind of amazing to me, it feels like the kind of thing that the hacker news crowd could solve in a long weekend.
Of course it must be more complicated than that, but even the basic user interface always feels wrong. Just let me push a button that has the candidates name on it or directly above it.
Oh well.
