When New York added the ability for voters to register online earlier this month, officials hoped it would add a lot of citizens to the state’s voter rolls. According to the office of Gov. Andrew Cuomo, fewer than 64 percent of eligible New York residents are currently registered to vote, which ranks the state 47th in the country in voter registration. The addition of the new online registration capability was especially timely, given the Aug. 19 deadline for those wishing to participate in the state’s primary election, scheduled for Sept. 13. “At the DMV, or in their own homes, New Yorkers will now have a convenient and secure way to ensure they are able to register and exercise their right to vote,” said Cuomo in a statement. And New Yorkers seem to have gotten the message. Twitter activity on Friday suggested that an influx of would-be voters brought the new system to its knees.
