Since the Affordable Care Act was passed in early 2010, I've held more than one opinion on just how the American public will feel about it as time goes by. Initially, perhaps influenced by the momentousness of the Act's passage, I wrote that once it was actually implemented, it would be much harder for Republicans to attack. They would no longer be able to frighten people with phantoms of death panels, and instead would have to talk about reality. Since people would have their own experience with the law to judge from as opposed to some hypothetical future, the attacks would lose their potency, Republicans would back off, and the law would rise or fall in public esteem on its own merits.
Then I began to have second thoughts. One of the biggest problems, which I wrote about a few months later, is that Obamacare isn't a single program like Medicare that people can come to love. It's a whole bunch of pilot programs and new regulations, many of which involve private insurance or existing programs like Medicare and Medicaid, and when people are affected by those changes they won't necessarily see them as being part of Obamacare. For instance, beginning in January, insurance companies will no longer be able to deny you coverage based on pre-existing conditions. But to most people, interacting as they will be with private companies, it will look like Aetna or Blue Cross or whoever just got more humane, and they may not even know that the government made them do it. Even the exchanges, if they work well, will just be the place where you go to shop for private insurance. Your relationship with the insurer you choose will certainly be affected deeply by the ACA's regulations, but most people still won't understand exactly how.
Among the consequences are that Republicans will be absolutely free to continue to blame every problem anyone has with the health care system on Obamacare, without concern of producing a backlash from the law's supporters.
