When Bernie Sanders took the stage Sunday night in Madison, Wis., the crowd of about 5,000 went wild. One of the biggest applause lines came when Sanders talked about his campaign taking on the establishment.
"These guys may have unlimited sums of money," the Vermont senator said. "They may control the media, they may control the economy, they may control the political system. But when millions of people stand up together united and demand change, we will not be stopped."
