The White House and the Department of Health and Human Services are not without shame and blame here. The website rollout was a mess. And the president’s repeated promise that people could keep their insurance if they liked it has turned out not to be true for many people in the market for individual, not group, policies — about 5 percent of the population.

It is true that the administration has forced insurers to offer more robust plans and many of the plans being canceled don’t meet the threshold, but it would have been better to be upfront about that than to deal with the fallout from nondisclosure on the back end.

That said, even these two issues are not the whole of the health care law and don’t mean it is destined to fail. And, perhaps more important, they haven’t much affected Americans’ opinions of the law. Americans may not know all the details or keep track of all the machinations, but they know a piling on when they see it.

According to a Gallup poll released Wednesday, the share of people who say the law will have a negative impact on their family or the country has remained virtually unchanged since the website rollout. The only notable change between June and October was a decline in the percentage of people saying that the law would make things worse for their families — a drop to 34 percent from 42 percent.

Republicans, with their incessant attempts to destroy, defund or defang the law using a barrage of spurious, unsupported allegations, have lost all credibility to be critical of the actual issues with the law’s implementation.
