... Wait for the Medicare For All bill to be analyzed by a respected and independent think tank

[Tom Rinaldo]

4. The original Medicare program was a non starter for decades...

Politically impossible, economically infeasible. Until it wasn't. Same with child labor laws. And clean air and water legislation, and so much else. The economics can be made to work if it is successfully sold to the public.

If the Republicans had invested a small amount of energy over the last 7 years into actually developing a plausible replacement for Obamacare rather than just running against it, Obamacare would already be history today. Their replacement could have been buggy, just somewhat plausible, and they would have had it in the bag today. Medicare and Social Security and pretty much every social safety net program introduced wasn't perfect out of the gate. It had to be returned to and subsequently modified.

Work is needed now to flesh out Medicare for All. This is a part of that process. It doesn't have to be politically feasible today. It just has to be ready for the day when political realities shift enough for it to actually stand a chance at passage.
