Debbie Wasserman Schultz has got to be hoping Hillary Clinton can take down Bernie Sanders in the primary.

Or it’s going to be a long road to November.

The chairwoman of the Democratic National Committee was mercilessly heckled while she spoke at a Democratic Party dinner in Manchester, New Hampshire Friday night.

C-SPAN cameras were trained on a man holding a flashing Bernie Sanders sign who sat stone-faced while the audience cheered Wasserman Schultz.

“We’re going to stand up and fight!” Wasserman Schultz shouted at a fevered pitched. “We’re going to make sure that every single American understands the choice that we have in this election leading up to November.”

The two men donning tuxedos in the background were clapping wildly for Wasserman Schultz while the Sanders supporter in a sweatshirt didn’t budge.

The shot cut away from the man just as he put his hand to his mouth to shout “you suck!” which was audible in the video.

“It is so critical, so critical that we focus on making sure that we can draw that contrast,” she continued in a softer tone, as if the man’s insult was sinking in.

It wasn’t the only incident of activists lashing out at Wasserman Schultz, who has been accused of shielding Hillary Clinton during the primary process.

Amanda Terkel from the Huffington Post reported the audience booed Wasserman Schultz’s name when it was mentioned.
