One problem is that voter turnout is generally low. And as far as I can tell, there is nothing in the system to stop a lot of fake ballots from being counted. And it's not possible to claim that a turnout of 75% is fraud, even if the usual turnout is around 50. Russian elections routinely get 95% turnout with almost no one going to the booths. There needs to be a way to verify whether a person has not voted. Could be based on SSN in some way. But it also has to be simple to use.
