MONTPELIER, Vt. — Vermont Secretary of State James Condos says critics of the elections system are vastly overstating the risks of voter fraud and election hacking as Election Day approaches.

The third-term Democratic secretary of state issued a statement on Tuesday.

Condos says he’s frustrated by some media speculation about the issue. He says widespread fraud would be highly unlikely in Vermont because municipal vote counting systems are not connected to each other or the internet.

He says tampering with voting machines’ memory cards would also be hard, because town clerks are instructed to keep their memory cards secure from the time they get them shortly before the election.

And a nationwide study found just 31 instances of potential voter fraud out of more than 1 billion ballots cast between 2000 and 2014.
