The city Board of Elections received over 400,000 mail-in ballots, but certified results released Wednesday revealed that only about 318,000 mail-in ballots were counted. That means about 84,000 people who attempted to vote in the primary did not get their vote counted — another example of the potential problems that could arise in November under a universal vote-by-mail system.

New York Gov. Andrew Cuomo (D) facilitated the high number of mail-in ballots with an executive order expanding the practice and providing pre-paid return envelopes to make it free and easy for people to vote by mail. The result was an extremely high invalidation rate and accusations of disenfranchisement.

From the Post:

"A 26 percent invalidation rate is astounding. It's very troubling," said Arthur Schwartz, who represented several candidates in a federal lawsuit claiming voters were disenfranchised over the BOE and Postal Service's handling of ballots.
