“At our convention, it was a matter of numbers,” Roberta Lange said on MSNBC’s “Andrea Mitchell Reports." "The Clinton people turned out 98 percent of their delegates. The Sanders people were short 500 delegates.

“They didn’t turn out their people. And so that was the division in the house that day, and that’s why Secretary Clinton won Nevada.”

Nevada’s Democratic presidential convention devolved into chaos on Saturday, with Sanders supporters loudly calling for delegate records and booing Sen.

Clinton ultimately edged out Sanders during the tense event, taking seven delegates to the independent senator’s five.

She now boasts 20 total delegates in Nevada to Sanders’s 15, expanding upon their individual results in the state’s Democratic presidential caucuses, held in February.

Reports emerged on Tuesday that Lange is receiving obscene messages and death threats following her role in last weekend’s chaotic convention.

Lange said she is troubled by the menacing messages.

“I’ve got threats to my family, my grandson, to my husband,” she said. "They’ve attacked the place where I have a daytime job. This is my volunteer job, being the chair of the party. They have attacked my workplace and said very awful things.”

The Nevada State Democratic Party on Monday warned that Sanders’s supporters could stir up similar turmoil during the Democratic National Convention in July.

Sanders on Tuesday blasted such accusations as “nonsense,” adding that Nevada’s Democratic Party had abused its influence and unfairly hindered his campaign.

“The Democratic leadership used its power to prevent a fair and transparent process from taking place,” he said in a statement. “If the Democratic Party is to be successful in November, it is imperative that all state parties treat our campaign supporters with fairness and the respect that they have earned.”

Clinton remains the Democratic presidential front-runner, boasting 2,240 delegates — including superdelegates who vote at the Philadelphia convention — to Sanders’s 1,473 out; 2,382 necessary for avoiding a contested convention this summer.
