In case you missed it — Warrencare and Petecare are, as proposed, structurally identical. Both are split into two phases. In phase one of both plans, the president passes a public option. Then, in phase two of both plans, private insurance potentially goes away, though in both plans phase two is entirely contingent — in Warrencare on passing a second bill, and in Petecare on the withering away of private markets.

Medicare for All, meanwhile, has a completely different structure: it combines the public option and the abolition of private insurance into a single bill. To put it another way, Medicare for All has no contingent phase two.
