> "would you favor that your employer-based healthcare would be rescinded and you would instead get healthcare from a new government controlled plan, where there would be no other options", which is the assumption M4A's viability is based on
No, that's just the condition for one proposal for Medicare For All.
As much as Americans complain about healthcare in general, most people don't want to give up their own health insurance once they have it. This is a known political trap that the previous M4A proposals walked right into, before crashing and burning.
When you say "Medicare for All" to people without details, they assume it means a Medicare option for all. When they start reading the details and realize they have to give up their current insurance, they don't like it.
