Except that Bernie has NEVER shut up about Medicare for All. Yesterday Bernie held rallies for Trump supporters in W. Virginia and Kentucky, explaining how repealing Obamacare would affect them and their families. At the Kentucky rally, Bernie announced that he will be introducing a Medicare for All Bill in the Senate when the Repub bill to eliminate Obamacare has been defeated. Bernie has never stopped saying that we need singlepayer.
Bernie explained that we need singlepayer (Medicare for All), and while we are trying to get Medicare for All passed, we need to keep Obamacare in place, inadequate though it is. Because if Obamacare is repealed, millions of Americans will lose their access to healthcare and to the services that are now provided through Obamacare and expanded Medicaid.
Bernie is doing his very best every day to improve the conditions of life for most of us in the U.S. But he's not a magician or the Messiah; he is ONE senator, and there are 99 other senators, all of whom are opportunists. Bernie is working 24/7 to wake enough voters to get progressives elected in 2018; without votes in Congress, Bernie can't get Medicare for All passed.
