Democrats of all stripes are embracing some form of "Medicare for All." Now they just have to decide what that means.
- For Sen. Bernie Sanders, it means scrapping the entire U.S. health care system and moving everyone into a pure single-payer system with no role for private insurance.
- For more moderate Democrats, it means letting people buy into the existing Medicare program (which relies on private insurers pretty heavily) or establishing a new public insurance option alongside private coverage.
