Sander’s Medicare for all is basically the European, UK Single Payer system, which has been more successful that the for profit system we have in America. The Sanders proposal would need to be discussed in congress with some compromises in order to get it passed. I don’t see any chance of it passing short of Democrats getting their stuff together again to win a majority in congress in 2018 and win the White House in 2020.
Will that happen? There will undeniably be a Trump backlash in 2020 because he has not only been a bad president from the very start, he has been absolutely horrific. What complicates this picture is the mainstream Republicans are starting to distance themselves from Trump as siding with him is going to set up other Republicans to get politically damaged in the Trump backlash. The ones that want to get re elected will start distancing themselves the close we get to the upcoming elections.
