Thousands of people who voted for Bernie Sanders in the Democratic presidential primary are expected to fill campgrounds around the party’s July convention for a movement to “Occupy the DNC.”

“We are getting phone calls constantly,” said Cheryl Robinson, who owns a stake in 200 short-term campsites at a Four Seasons in Pilesgrove, N.J. “A lot of times they don’t want to let us know that they’re Bernie supporters,” she told the Associated Press. “We ask if they’re coming for Occupy the DNC, and then they kind of giggle and embarrassedly say, ‘Yes, we are.'”
