Gov. Andrew Cuomo rapped the New York City Board of Elections for posting personal information of 4.6 million voters on its website amid concerns about hacking and identify theft.

“I think it was a mistake. Putting people’s personal information online in this new world where we’re worrying about hacking, we’re worrying about identity theft etc, I don’t think it’s a good idea,” Cuomo said following a bill signing at Jones Beach.

“I think people can use it for bad effect one way or another. I don’t think it’s a good idea, but I have nothing to do with the Board of Elections, either,” he added.

In February, the board published the names, addresses and party affiliations of active registered voters on its website.

The board acted after the Legislature passed several election reform bills, including consolidating state and federal election primaries on the same date in June.

A board spokesperson defended its decision, saying it had to post the names on the web to comply with a tight deadline in the new law.

“The board has historically printed the public enrollment books as required by April 1st. To accommodate the consolidated primary date in June, the enrollment list publishing date was moved from April 1st to February 1st by the NYS Legislature,” said spokeswoman Valerie Vasquez.

“Given the late notification of the publishing date change, it was not possible to meet the February 1st date. Permission was granted to make the enrollment lists available on the board’s website.”

The same voter data has always been available, but only at the board’s offices.
