While discussing Hillary Clinton, Mitchell stumbled, "It is her trying to walk the line between the far more progressive and far more–  I don't know what to call them other than the progressive policies – of Bernie Sanders which have caught fire certainly in Iowa."  Mitchell "doesn't know what to call" the policies of Bernie Sanders?  Bernie Sanders has repeatedly called himself a socialist. So, how about starting there?
