Harry,
Medicare for All is the same as Medicare for those over 65.  It's a single-payer system eliminating the "middlemen"-the profiteering private insurance companies.  It's like the Canadian and Australian single-payer systems.  The doctors and hospitals are still private sector.  Whereas in the British healthcare system, the doctors and hospitals are public sector like our V.A. medical care system.
Now compare Medicare with "Trumpcare".  Even Mitch McConnell gave up on that "loser".  All those poorly educated voters that believed in Trump would have lost their free Medicaid they have now.
Trump was born with a silver spoon and knows nothing about the real world.  He does know how to use creditors' money to make more money, exploiting the bankruptcy and tax laws.
Everyone knows Obamacare was only a first step, a "foot in the door" to achieve a single-payer system.
