"That's so disgusting," Sarandon said in an interview with Jordan Chariton of The Young Turks, a popular progressive online network. "The critical question is, does it matter?

"A lot of people felt disenfranchised. A lot of people are working so hard and getting nowhere. A lot of people are sick with politics the way it is," she said. "And Bernie and Trump spoke to those people.”
