This is what happens when you have a generation of young people whose central experiences with capitalism have been two recessions, a financial crisis, crushing college debt, flat wages and soaring income inequality. For young people, the devil they don’t know is looking better and better than the devil they do—and that sentiment is fueling insurgent challengers.

Many of these candidates continually emphasize the need to purge U.S. politics of corporate money, starting with the Democratic Party.

“It’s easy for candidates to say they’re for overturning Citizens United, but it’s really meaningless when they’re also taking so much corporate and dark money that they’ll never follow through,” says Tim Canova, who is running for Congress in Florida’s 23rd congressional district. “The Democratic Party has lost its way. It has gone corporate and Wall Street on so many issues that it has unfortunately turned its back on its own grassroots base.”

And it’s more than a matter of principle: Many of these candidates believe that voters are fed up with how the corporate capture of the party has pulled it to the right. “The Democratic Party has been Lucy with the football and the voters have been Charlie Brown,” says Tom Fiegen, a candidate for Senate in Iowa. “Democrats have pulled the football away too many times, so the voters say, ‘Nope, I am not going to be tricked again. I am not going to have you lie to me and tell me you’re on my side, and then when I send you to D.C., you vote for the TPP or you vote for the Keystone Pipeline.’ ”

Nowhere is this trust gap felt more keenly than among young voters. Sanders has won the support of young people like few politicians before. In each of the 27 states that held primaries or caucuses in February or March, he won the youth vote, often by more than 50 points. In his home state of Vermont, he defeated Hillary Clinton among voters under 29 by an overwhelming 95 percent to 5 percent.

Tom Fiegen saw how this played out in Iowa. “In the conventions I went to,” he says, “there was probably 30 to 40 years difference in age between Bernie supporters in one half of the room and Hillary supporters in the other half of the room.” Fiegen himself has endorsed Sanders, and you can hear in his voice the same passion that has animated so many young people: “We are idealists. … We want a better world. We think we can achieve it. We’re willing to basically throw our bodies in front of the bus to do that.”
