Story highlights Hillary Clinton won the California presidential primary

Actresses Shailene Woodley and Rosario Dawson, who are die-hard Sanders supporters, attend the Democratic National Convention.

On Monday in Philadelphia, the delegation's Sanders contingent was loud and rowdy and hanging to a small glimmer of hope. Grouped throughout the California section of the arena, some of the loudest delegates had sat directly behind Sen. Barbara Boxer. They disrupted the proceedings all evening and it got to the point that a frustrated Sarah Silverman - comic and ardent Sanders supporter- turned to them and essentially told them to shut up from the stage.

On the second day on the convention, the Clinton supporters in the delegation were more prepared. They made sure that they arrived early to the Wells Fargo Center, filling up the first ten rows. It wasn't just that they were now pushed up further from the floor, the Bernie supporters also looked tired as the reality of the day began to set in.

California delegates and actors Rosario Dawson and Shailene Woodley sat together quietly watching the clock count down.
