The Democratic National Convention in Philadelphia has not yet brought the party to unity like its leaders might have hoped. The DNC’s first day of caucuses, councils and speeches served to illustrate the divide that the party feels between Sanders supporters and Clinton supporters.

Though Vermont Sen. Bernie Sanders voiced his support for Hillary Clinton and ended his campaign for presidency long ago, many of his most enthusiastic followers took the DNC as the opportunity to protest what they feel was an unjust Democratic presidential nomination.

The Democratic Party’s system of “superdelegates” has long been under fire, and even Republican nominee Donald Trump has argued that the system seems to have stacked the odds against Bernie Sanders.

Sanders supporters held up “Bernie or Bust” and “Never Hillary” signs, chanted “Bernie! Bernie! Bernie!” whenever his name was mentioned and booed at nearly every reference to Hillary Clinton’s name.

 

The stage was filled with attempts to appeal to either side of the argument.

“To the ‘Bernie or Bust’ people, you’re being ridiculous,” said comedian Sarah Silverman, who had just spoken her support for Clinton.

The unrest was further exasperated with the release of several thousand hacked emails between DNC officials. Many of the emails showed an overt bias within the Democratic Party for Clinton’s campaign and even attempts to undermine the legitimacy of Sanders’s campaign.

Clinton’s campaign responded to the emails by arguing that the leak was a result of Russian hackers seeking to her own campaign and bolster Republican nominee Donald Trump’s.

As a result of this major breach, Rep. Debbie Wasserman Schultz, DNC chair, announced her resignation Sunday.

North Carolina delegates to the convention argued that the DNC chair’s resignation was appropriate and could help bring the party together. But nonetheless, the  delegates remain divided.

Sanders, attempting to quell the turmoil among his advocates, appealed to those upset people in his speech.

“I understand that many people here in this convention hall and around the country are disappointed about the final results of the nominating process,” Sanders said. “I think it’s fair to say that no one is more disappointed than I am.”

“Any objective observer will conclude that… Hillary Clinton must become the next president of the United States,” he said.

Additionally, Sanders sent a message to some his delegates in which he encouraged them not to cause further uproar during tonight’ events.

“Our credibility as a movement will be damaged by booing, turning of backs, walking out or other similar displays,” Sanders said in that message.
