Hillary Clinton’s not a gracious winner.

Despite besting Bernie Sanders in Nevada over the weekend and being seemingly poised to trample him in South Carolina, Hillary is nonetheless on the attack against the 74-year-old socialist senator.

In her latest campaign email, she’s now accusing her opponent of effectively undermining victims of the Sandy Hook school shooting.

Deeming them “real differences” with Sanders, she writes:

In 2007, Senator Ted Kennedy made a valiant effort to pass immigration reform — I stood with him and voted for that bill. Senator Sanders voted against it.

This week, families from Sandy Hook are in court suing the manufacturer of the gun that killed their children, challenging the law that gives gun-makers legal immunity. I voted against that law. Senator Sanders voted for it.

And right now, Senator Sanders is running a campaign based largely on a single issue — but I don’t think we’re a single-issue country. We need a president who will break down the barriers facing all Americans, from economic inequality to systemic racism, sexism, and homophobia.

“I’m going to keep fighting my heart out to win every vote,” she ends.

Sanders, meanwhile, is throwing limp-wristed punches in return.

During a recent campaign rally, he shushed the audience when they jeered the mention of her name.

“No, no, no,” he said repeatedly when the crowd reacted negatively to her name.

“I respect Secretary Clinton. We can have differences,” he said.
