Before Sen. Bernie Sanders (I) officially won his Democratic nomination in Vermont on Tuesday, he sat down with Stephen Colbert on The Late Show. Colbert asked why he wasn't in Vermont — Sanders said he'd voted that morning — and what democratic socialism means for Sanders and his allies. Sanders said it mean a $15-an-hour minimum wage, a national right to health care, tuition-free public college, and clean energy. "Other people have espoused those ideas without calling themselves socialists," Colbert noted.
