Read an interesting bloomberg article that supports what I believe to be the case since the ACA went into effect, that Republicans opposition to the ACA is only half-hearted at best, because if the ACA were repealed all eyes would be squarely on them to come up with an alternative. It's obviously a requirement to come out firmly in opposition to the ACA in order to win a Republican party, and routinely register votes to repeal it to protect yourself in the next primary, but I think they would collectively shit themselves if the onus was put on them to come up with a credible alternative. When the marketplace descended into chaos after such a repeal, they would obviously do their best to blame it on Obama for ever passing the ACA in the first place, but I think most would agree that would gain little traction beyond their base. The individual mandate, which was a conservative policy prescription until Obama signed his name on it, would obviously be off the table, so what would the Republican response be after they are done congratulating themselves for eliminating health insurance for 10M+ people in the name of freedom? Extend the ACA provisions until they came up with a viable alternative? Republicans have not prepared for repeal any more than Obama has, which is interesting since they are the ones advocating for it. I can only surmise that is because they have never realistically considered that it may happen, so it is therefore just rhetoric.
