Out of nowhere, Bernie Sanders appeared on Stephen Colbert's "Late Show" cold-open sketch last night.
After Colbert has his arm caught in a vending machine trying to retrieve a Kit Kat bar, the Vermont senator and Democratic presidential candidate arrived to teach him a lesson in perseverance.
"I don't take money from billionaires, but I do check every vending machine change slot," Sanders said, though he found no change and promptly walked away.
He returned to talk about Tuesday's primary in West Virginia, where "I think we've got a shot to win."
"Even if you do well tomorrow, the delegate math is against you," Colbert reminded him.
"It's a narrow shot," Sander rebutted. "But we still have a chance to win a majority of the pledged delegates, we're gonna fight for every last vote, and at the end of the day, I hope and believe that we are gonna win this."
