By voting to repeal the ACA over and over and over again, even though it had zero chance of being signed by Obama, the Republicans managed to keep the possibility alive.

Go to Reddit and read the rightwing political subs. They certainly don’t think it’s a given there. They may not like the new bill, but they hate the old one, and if some there had their way, ACA would be repealed and not replaced.
