#More than 1 million NYC residents have now voted early

More than 1 million Big Apple residents have cast ballots during the city’s nine days of early voting — or about 20 percent of those registered at the polls, officials said Sunday.

The million mark was reached at 9 a.m. Sunday, the final day of early voting, and represents more than a third of all of the 2.7 million city voters who cast ballots in the last presidential election.

In terms of absentee ballots, 1.1 million city voters requested them for this year’s race — and more than half have already returned theirs, officials said.

That means that if roughly the same number of city residents vote in this year’s general election as in 2016, more than half have already cast their ballots.

The city was plagued by horrendous lines in its first few days of early voting, which Doug Kellner, co-chairman of the New York state Board of Elections, told The Post is “unacceptable.

“They did not provide enough polling sites,’’ he said of the city. “Hopefully, we learn from this experience and don’t repeat it during the presidential election four years from now.’’

On the positive side, Kellner said the city BOE’s equipment — poll pads to sign voters in and ballot scanners — apparently held up because there haven’t been complaints of malfunctions.

Kellner predicted that there will still be some lines on Election Day at polling sites with election districts that have 1,000 or more voters registered.

But he said he hopes there may be a reduced volume because so many voters cast ballots early.

Early voters at Madison Square Garden on Sunday were among those enjoying shorter waits.

“I was surprised there weren’t big lines,’’ said Liz Wexler, 38, who brought along her dog, Linus.

“I thought maybe I should wait [till now] because New Yorkers are so on top of everything that they’re trying to get everything in right away and maybe it will be quieter on the last day.”

Nearby, Macy’s joined the group of retailers in the city boarding up their stores in case of rioting over who gets elected.

Michael Sollenberger, 39, who works in tech at The Real Real and voted at MSG, said, “All of our retail stores have been boarding up.

“Hopefully it’s nothing. … But with the climate, it’s kind of expected, unfortunately,” he said of the potential unrest.
