Something’s rotten in the Big Apple for Hillary Clinton.

An uncomfortably close shot of her death stare goes viral. The “Bernie or Bust” movement grips the nation. A new poll shows her big lead in New York dwindling.

What’s next — an email disclosing her undying love for David Ortiz?

All of this is happening in Hillary’s backyard, just a few weeks before she was supposed to finally stamp out The Bern in the April 19 primary. And once again the Clinton campaign is sweating it out and being forced to lower expectations.

This isn’t about Hillary losing her grip on the nomination. The Democratic Party and much of the media have handed her that already — inflating her delegate lead with “superdelegate” totals and lapping up the Clinton spin minimizing all of Bernie Sanders’ state victories. It really doesn’t much matter what Democratic voters say anymore.

But Hillary needs New York to love her. It’s the biggest delegate haul so far and a diverse electorate. Independents can’t vote.

And more importantly, it’s Donald Trump’s turf, too. If Hillary thinks wagging her finger at an innocent young Greenpeace activist is rough, wait until she hears the taunts from Trump for losing their beloved home state. Especially if the blustery billionaire wins the GOP side of the ballot. Talk about bragging rights.

Then there’s the tabloids. They’ve had a field day with Trump, but for the next 2 1⁄2 weeks they’ll be dogging Hillary, practically daring her to lose it again. And in the unlikely event she actually loses to Sanders in New York, the front-page headlines will be merciless.

The voters in New York can be tough, too. It’s not like New Hampshire, where they welcome the candidates into their living rooms. New Yorkers will ignore them. And if a candidate causes a traffic jam, they’ll give them the finger.

But the real aftershocks from the New York primary may not be felt until the fall. A poor performance from Clinton on April 19 will be a bad sign for her general election campaign.

New York is a gimme for Democrats. It’s got even more liberals than Massachusetts. But large parts of the state are also packed with working-class Democrats in cities like Buffalo and Binghamton — exactly the type of voters who have shunned her campaign in the primary.

That’s why the New York primary is important for Clinton. It’s not going to decide whether she wins the nomination. But if Hillary can’t make it here, she won’t make it to the White House.
