Mark Ruffalo is starring in a new video released by Bernie Sanders’ campaign, explaining why he supports the Democratic presidential candidate.

“Bernie Sanders comes to us in a moment of a crisis of credibility in the American political system,” the Spotlight and Avengers star says in the video, appearing alongside director Matthew Cooke.

“People feel like they have given up on the system, and that is exactly what the bad guys want us to do, they want us to give up on the system,” he adds.

Cooke says Sanders’ campaign has “sparked a fire,” while Ruffalo tells him, “This is the future of the Democratic party. We want to take care of each other.”
