'We Made History': Watch as Sanders Addresses His 1900 Delegates

“Make no mistake about it—we have made history,” a hoarse Bernie Sanders told a room full of adoring delegates on the first day of the Democratic National Convention (DNC) in Philadelphia on Monday.

“We have shown the entire world that our ideas are not some crazy, wild, utopian fantasies,” he said, “they are ideas supported by working people from one end of this country to the other.”

Sanders, who ticked off a list of primary season accomplishments—including winning 13 million votes and the support of 46 percent of pledged delegates—elicited cheers of “Bernie! Bernie!” when he said: “We’re not fringe players anymore!”

His line marking the resignation of Democratic National Committee chair Debbie Wasserman Schultz also drew huge applause.

But when Sanders declared, “We have got to elect Hillary Clinton and Tim Kaine,” he was met with boos.

“We want Bernie!” the crowd shouted, as he outlined the reasons why Donald Trump must be defeated.
