Watch: Bernie Sanders Makes His Case to Colbert in Most Charming Way Possible

“You’ve got to believe, Stephen. You’ve got to rock the system.”

With West Virginia voting in its primary Tuesday, Bernie Sanders appeared on Stephen Colbert’s “The Late Show” Monday night to make the case that he still has a shot. The whole skit took place around a vending machine that was denying Colbert his candy.

“Here’s the story,” Bernie told him about why he is not giving up. “It’s a narrow shot, but we still have a chance to win a majority of the pledged delegates. We’re going to fight for every last vote. And at the end of the day, I hope and believe that we are going to win this.”

His arm wedged in the vending machine slot, Colbert was skeptical. “But at a certain point, don’t you have to say, I’m not going to get the thing that I want?” he asked.

The 74-year-old Sanders is getting pretty used to questions like this.

“You’ve got to believe, Stephen. … You’ve got to rock the system,” Sanders said, jostling the machine and releasing the 100 Grand candy bar.

“I don’t take money from billionaires, but I do check every vending machine change slot,” the Democratic candidate joked. Well played.
