A Sanders delegate, Dr. Talat Khan, walks into a room with a Clinton delegate, Mary Jane Sanchez. And, they hug.

"Bernie, Hillary, we stay in the same room," says Khan. "We're friends. We went to the Obama convention in the past and enjoyed it. This time we enjoyed--we are great friends."

The Clinton campaign and party leaders have spent the week trying to encourage this kind of affection to replace the arguing and bitterness that punctuated the convention.

Daraka Larimore-Hall is both secretary of the California Democratic Party and a Sanders supporter. He's telling delegates to work within the system.

"We fought really hard, and we're starting to change the party in some really profound ways. And I think we should be celebratory, and happy, and proud, and be trying to move more Hillary delegates over to a progressive agenda, and in a state like California that's not hard."

For some Sanders delegates, the so-called Bernie or Busts, working with Clinton is a non-starter.

Political consultant and Clinton delegate Steve Maviglio says at this point it's not worth engaging those supporters.

"The Bernie Sanders people, as a Pew Poll showed, 90 percent of them are already on board. What we have at the convention is the extreme of the extremes. They're probably not going to vote for Hillary Clinton, and that's okay, if that's the way they think that should go."

Maviglio says, realistically, Clinton has to turn her attention to four or five swing states, not the California vote.
