CNN article, is Bernie Sanders right about 'single payer system' healthcare?

The only type of health care system that does work for any nation, is a single payer system, so yes, Bernie Sanders is right.  That said, Bernie Sanders is just regurgitating the things Ralph Nader said in the decades before Bernie's run for President.  As I've been pointing out, Bernie Sanders is just here to fulfill the Ralph Nader component  of the election, as Ralph Nader is now too old to run.  There will be no Bernie Sanders presidency, there will be no single payer system, but there will be more medical tyranny.  Bank on it.
