21 percent of NYC primary mail-in ballots disqualified

More than 84,000 mail-in ballots in New York City's Democratic presidential primary were disqualified, the city's Board of Elections said.

The Board of Elections reported that it received 403,103 mail-in ballots for the June 23 primary. The certified results released on Aug. 5 revealed that 318,995 mail-in ballots were counted.

That means 84,108 ballots were not counted or invalidated — 21 percent of the total.

"One out of four mail-in ballots were disqualified for arriving late, lacking a postmark or failing to include a voter’s signature, or other defects," the New York Post reported.

The Post reported on Aug. 4 that roughly 30,000 mail-in ballots were invalidated in Brooklyn alone.
