The first time I remember people making comments of this nature on tech sites was close to 20 years ago, when in the aftermath of the 2000 elections, some said electronic voting was the answer, but the companies promoting such solutions seemed universally slimey and not security conscious.

I don't think anything has changed since those days.

I think part of the problem has got to be that non-experts cannot judge how good a security solution is, so local governments are ill equipped to view it with a skeptical eye. There might also be in some way a downside of federalism here - if the states pooled more resources perhaps they would be able to solve the problem once instead of 50 times.
