What if it is not a public record? Also, even if it is a public record, how can you be sure that people in the voters list are real, they are eligible to vote in this region and not made up by authorities? Also, even if the list of people who voted is public, and if results were falsified, with electronic voting you cannot estimate the scale of falsification. Did they alter just a hundred of votes or hundred thousands.
