Vermont Senator Bernie Sanders unveiled his latest ‘Medicare for All’ proposal Wednesday; announcing his plan to transform Medicare into a full-fledged universal healthcare program during a four-year transition that would eliminate private insurance companies.

“Sanders’ plan is the most ambitious by far of Democrats’ slate of bills aimed at expanding health coverage, proposing a total restructuring of the the national health care system that would effectively eliminate employer sponsored insurance and other government programs like Medicaid,” reports Politico.
