Shailene Woodley Leads Cross-Country Road Trip to the Democratic National Convention

The "Divergent" actress has been a vocal and active supporter of Bernie Sanders.

“It doesn't matter what your cause is. What your issue is. What you stand for or feel oppressed by. ALL issues are united in this movement,” the official website for the road trip reads. “Every movement is unified in our message: it is UP TO US to write the narrative we want our future generations to be born unto. This is our MODERN DAY PEACE TRAIN.”

By midweek, one of the organizers, Heidi Harmon, said the caravan had grown to about 100 people, many traveling in RVs and decorated cars.

“The overall goal is to really keep the movement moving,” Harmon, a Sanders delegate, said, speaking to ABC News from somewhere between Boulder, Colorado, and Lincoln, Nebraska. “The Bernie Sanders movement is a really inspired moment in our political history and we don’t want people to feel disheartened.... We want to remind people about what Bernie has been saying this whole time. It has never been about him, it has always been about us.”
