The City Council voted Thursday to require the Board of Elections to send voters texts and e-mails telling them when their poll sites change and reminding them of upcoming elections.

Under another bill passed by the Council, BOE will have to set up a website and mobile app to let voters check their registration and party affiliation, and change information like their address.

During April’s presidential primary, many voters had no idea they had been dropped from the rolls or from their party until they arrived to vote. There’s currently no way to check online.

“Tens of thousands of voters showed up to vote thinking they were registered or registered with a political party, only to be told by election workers they were not in the poll books,” said Councilman Ben Kallos (D-Mahattan). “Voters should be able to easily access information about elections at any time.”
