Bill de Blasio was elected mayor of New York City for a second term this November over his opponent, Republican Nicole Malliotakis, who said she welcomed the president’s support of her candidacy. But, it turns out, when it came to the Trump family, Donald Trump was the only member who even might have cast a viable ballot on Election Day. Per the New York Daily News, Melania Trump, Jared Kushner, and Ivanka Trump all, by their own error, did not have votes that counted.

According to officials at the Board of Elections, Trump signed and dated an absentee ballot dated October 19. The First Lady also filled out the ballot in block capital letters, but she neglected to sign the envelope in which the ballot was enclosed.

As the Daily News noted, the instructions from the B.O.E. are pretty cut and dry; easy enough for an out-of-state college student juggling the stress of midterms to figure out and mail to his or her home state:

“After making your votes on the ballot, fold the ballot and put it in a smaller envelope. Sign and date the back of the envelope. Seal the envelope and put it in the larger envelope that is addressed to the Board of Elections. Mail or deliver your ballot to your borough Board of Elections office.”

But the First Lady’s ballot had no signature and was, therefore, an invalid vote. Ivanka filled her ballot out correctly, but she didn’t mail it in until Election Day—not far enough in advance. The B.O.E. said Kushner never sent in his ballot.

Trump could have filed a usable ballot, but for now it’s a gray area. He sent in a ballot properly signed, but he got his birthday wrong. Trump’s birthday is June 14, 1946—he’s a Gemini, but that’s an entirely different bag of astrological worms—and instead the ballot read July 14, 1946. The Daily News said it was “not immediately clear” whether this would have any effect on the ballot.

Regardless, the president’s opinion on de Blasio still exists—with the rest of his others—on Twitter.
