Robby Mook isn’t the only one spooked at the Clinton campaign headquarters.

Spokesman Brian Fallon is joining in on the pant-wetting after a new round of battleground state polls show Trump winning or tied in Florida, Pennsylvania and Ohio.

“We know the battlegrounds are going to be close til the end,” Fallon tweeted. “That’s why we need to keep working so hard. Trump is a serious danger, folks.”

Politico reported on the polls:

The race is so close that it’s within the margin of error in each of the three states. Trump leads by three points in Florida — the closest state in the 2012 election — 42 percent to 39 percent. In Ohio, the race is tied, 41 percent to 41 percent. And in Pennsylvania — which hasn’t voted for a Republican presidential nominee since 1988 — Trump leads, 43 percent to 41 percent.

In late June, campaign manager Robby Mook sent a panicked email to supporters, saying their fundraising numbers keep him up at night.

He wrote:

I don’t want to be hyperbolic — but I do want to be honest with you about where we are. And the truth is, as of today, we’re 130,000 donations short of our goal.

This goal isn’t some kind of generic oh-it-would-be-nice-to-get-there sort of thing. You know that’s not how we do things on this campaign.

This is about actual projections and budget decisions: If we don’t raise what we thought we would for June before tomorrow at midnight, we’re going to have to make some difficult calls about where our funding goes in key battleground states, whether to hire more organizers or cut back, or whether to set up that next field office.

“And the reason I feel so much urgency about this is because of the nature of the challenge we’re up against,” Mook wrote.

“I’ve lost elections before. I know how bad that feels. But I’ve never worked a race where I’ve spent more nights sitting awake, stressed about the implications of what losing might mean. Donald Trump isn’t a normal candidate, and if he beats us, it will be more than a defeat at the ballot box — it will be a once-in-a-generation setback for our values and our shared idea of what America means,” the email said.
