Sanders’ Senate version was released in a press conference supported by many DLC and “moderate” senators. The “centrists” are able to support it because it vague about financing (much of which will come from savings from ending Romney/Obamacare, though it doesn’t state that) and it includes premiums and taxes (in unstated amounts). It does however, offer various options for workers who would lose their jobs in a slow transition period. Also it leaves long-term care in the hands of the states (to placate the nursing home industries, especially in Cali and NY).
Most critically it leaves the details and regulations up to the HHS Secretary to implement – which means, as it is written, it would be in the hands of Trump’s HHS Sec Alex Azar - a former drug company executive to implement. Or imagine any of the Dems’ potential choices since they are on the medical-industrial complex payroll as well.
Because of the weak implementation language it would invariably be tied up in courts, reverting to Obama/Romneycare for millions. It’s an invitation to disaster, but allows Dems to vote for “Medicare for All” while never achieving it.
Because of its financial vagueness and the power it gives to the HHS Sec, it is very much a pig-in-a-poke – unlike true Single Payer which is clear about cost-savings, is paid for by taxes, does not include long phase-ins or voluntary “buy-ins” and “public options.” This is a PR document, not a Single Payer health insurance for all bill.
