PHILADELPHIA – Bernie Sanders was booed by his own delegates after calling on them to support Hillary Clinton on the opening day of a Democratic National Convention that is proving more contentious than expected.
The reaction Monday demonstrated the work left to do to bridge the ideological divide in the party, even as Democrats kick off a convention meant to demonstrate how much more unified their party is than the GOP.
The moment was also a definitive one in Sanders’ career, showing he’s more pragmatic than he's often given credit for, even as he stokes the flames of a political revolution that threatens to overrun its leader.

According to a recent NBC/WSJ poll, 76 percent of Sanders supporters said they would vote for Clinton against Donald Trump. But the vocal activists filling Philadelphia's streets and convention spaces made that number feel much smaller.
The meeting of Sanders delegates Monday afternoon took on the feel of a vintage Sanders rally, including speeches from surrogates Rosario Dawson and rapper Killer Mike.
Dawson, one of Sanders’ most vocal and acidic surrogates during the primary campaign, urged supporters to “stay the course” and called for the removal of interim Democratic National Committee Chair Donna Brazile, who replaced ousted chairwoman Debbie Wasserman Schultz only Sunday.

Wasserman Schultz, who was jeered off the stage at a meeting of the Florida delegation Monday morning, will now no longer even gavel in the convention.
When Dawson mentioned Clinton, who is set to formally receive the Democratic Party’s nomination Tuesday, the crowd booed. “I have said before, and I stand by it: She is not a leader, she is a follower,” Dawson said.
But the audience, nearly 1,900 Sanders delegates along with some supporters and volunteers, came to see Sanders. They roared with approval when he took the stage to trumpet the successes of his campaign and the revolution he galvanized.
“Make no mistake about it, we have made history,” he said, touting real accomplishments on the party platform and rules committee, as well as the removal of Wassermann Schultz. “We're not fringe players any more.”
Sanders laid out a game plan to continue the “political revolution” long-term but said it had to start by stopping Donald Trump.
“Immediately, right now, we’ve got defeat Donald Trump. We’ve got to elect Hillary Clinton and Tim Kaine,” Sanders told the packed room.
The crowd erupted into sustained boos, which drowned out some cheers. Sanders seemed taken aback and stood for a long pause before moving on with his speech.
“Brothers and sisters. This is the real world that we live in,” Sanders continued, warning that Trump was far too dangerous to be given a pass.

The crowd seemed stunned as well. It fell into quiet murmuring before eventually growing into chants of “We want Bernie!” and “Take it to the floor!” -- suggesting they wanted Sanders to contend Clinton’s nomination for the Democratic Party.
