If Sanders can turn blacks and Hispanics against Capitalism, he can win. Sanders' greatest foe is American mythology.
Clinton's best shot is to embrace Capitalism straight out but argue it has been hijacked. Clinton's greatest strength is style. Sanders comes off as a grumpy one issue old man. Right or wrong is irrelevant in politics.
Sanders needs a very active Elizabeth Warren on the ticket. She has great style. He should appoint her NOW so she can campaign for him.
It will be a fun battle to watch. Political theater.
