Wrong on all counts. He did label himself a 'Social Democrat'

Some programs should be socialized which meant it was available to all by our tax dollar rather than individuals bearing the entire burden like education, healthcare (like Medicare for all) These are all social democratic programs and listed in our party platform. Bernie has no long term goal of a "Nationalized economy", only income equality. Democratic socialism is not antithetic to capitalism and never was. Republicans tried to equate the mention of socialism with communisms but only those uninformed would try to equate democratic socialism as government controlled rather than regulated per the people's vote through elected representatives. We already have democratic socialism which we the people regulate by our democratic freedom to choose.
