It depends on how sloppy they were and whether the results were available for review afterwards. Some years ago there Venezuelan dictator Hugo Chavez "graciously" agreed to a referendum to remove him from office--which he of course won. Afterwards, people going through the results from the electronic voting machines (which had been made public for token international oversight) they used realized that his people had rigged them to fake votes in an easily detectable pattern.
Electronic voting is fairly notorious for lack of security. I'd just take it as a given that what they're really showing is who tampered with them last, and nothing more.
