Over a month into the implementation of the Affordable Care Act there seems to be no increase in the number of people who feel they have been helped by the law. In fact there has been a modest increase in the number who think they have been hurt by the law. From Gallup:

Effect of Healthcare Law on You and Your Family So Far, February 2012 vs. November 2013

This is the exact opposite of what Democrats were hoping for.

This is also why I think it is unlikely the law will become very popular even if the Obama administration can get the system working smoothly. The law was not designed to directly impact most people, so most people probably will never have a personal experience with the law that will convince them to rethink their long held opinions about it. In addition, there is a significant segment of the population that is convinced the law has hurt them and it is unlikely anything will change their mind.

Things like the Medicaid expansion will help many people but that group still make up only a small percentage of the country as a whole.
