Maybe it worked in New Hampshire & Minnesota.
My son is a computer whiz who says it was common knowledge among geeks that the machines were eminently hackable, either locally or centrally i.e. most of the machines in the country could be altered from a single location by a technique called proportional voting or proportional scoring. He says frustration of the hack was worked but many computer whizzes like himself only better at it who worked hard to block it. He says he started to get into it but better geeks than him were on it and he stayed out of it.
