The Hillary Clinton campaign appears to have officially hit the panic button over a potential loss to Bernie Sanders in the early primary state of New Hampshire.

“The primary race in New Hampshire is neck and neck — a loss there could be a sharp blow to all the work we’ve done,” Clinton writes in an email to supporters Saturday. “We’ve got the momentum to carry this win, but our folks on the ground still need the resources to put us over the finish line.”

In the email titled, “A Sharp Blow,” she adds, “There’s a lot riding on the New Hampshire primary in just one month. It’s going to be close, but I’m ready to do this.”

The campaign’s asking for contributions for as little as $1, despite raising $100 million in 2015.

On “This Week” Sunday, host George Stephanopoulos picked up on that theme.

“Things are so close in Iowa. It looks like a real race right now — real race in New Hampshire,” the former Clinton staffer told the panel.

“The Clinton campaign seems to be bracing for losses in Iowa and New Hampshire,” Stephanopoulos added. “They still hope they can pull out Iowa but you hear a lot of talk about how this is a delegate fight and this is going to take a long time.”

The Saturday email was the second in less than a week in which the campaign appears to be spooked.

On Wednesday, campaign manager Robby Mook wrote:

News just broke that Bernie Sanders is outspending us on TV in Iowa and New Hampshire by hundreds of thousands of dollars.

I’m worried, because last-minute ads could cost us this election. And I’m annoyed — because once again, they’re counting on this team staying on the sidelines. …

They’ve got more donors than we do, more contributions than we have, and if they keep up this pace on TV, they’ll be able to get their message out to more people than we can.

“Worried” and “annoyed” are generally not to words a confident leader uses to inspire his troops.

A Fox News poll published Friday shows Sanders has a 13-point lead over the former secretary of state in the state.

Sanders, who was up by one point in mid-November, has now broken the 50% threshold, leading Clinton 50-37 among Democratic primary voters.

Sanders is leading among women — the group Clinton is overtly courting. He’s up by seven points, while also leading with men by 23 points.

Even if Clinton ekes out a win in the Granite State, she may have problems long term.

“While 79 percent of Clinton supporters would be happy with Sanders as the nominee, only 56 percent of his supporters would feel that way about a Clinton win,” Fox News reports.

No wonder Mook is “worried” and “annoyed.”
