I would disagree about warren and Sanders - their plans are unworkable socialist fantasies.
Bernie spent his honeymoon in soviet russia drinking with the Communist totalitarians - and has made millions in a capistalistic fashion selling communism to foolish Americans.
Warren has Marxist financial advisors - formerly advised French president hollande in socialist/Marxist economic principles - even the French would not tolerate what a wreck they made of the French economy.
I have a different opinion of the DPST Marxist front-runners - they are far more dedicated to the Communist manifesto than to the Constitution and bill of Rights.
IMHO.
Neither leading party is proposing anything reasonable as a constructive improvement on the ACA and its hideous costs and bureaucratic micro-management. Which adds another layer of cost to medical care in America. The ACA does protect those with pre-existing conditions - which is a necessity for includsion in any comprehensive health plan for America.
Again, IMHO
Thanks SR
