It’s said that you can judge a man by the quality of his enemies. If the same principle applies to legislation, the Affordable Care Act — which was signed into law two years ago, but for the most part has yet to take effect — sits in a place of high honor.

Now, the act — known to its foes as Obamacare, and to the cognoscenti as ObamaRomneycare — isn’t easy to love, since it’s very much a compromise, dictated by the perceived political need to change existing coverage and challenge entrenched interests as little as possible. But the perfect is the enemy of the good; for all its imperfections, this reform would do an enormous amount of good. And one indicator of just how good it is comes from the apparent inability of its opponents to make an honest case against it.

To understand the lies, you first have to understand the truth. How would ObamaRomneycare change American health care?

For most people the answer is, not at all. In particular, those receiving good health benefits from employers would keep them. The act is aimed, instead, at Americans who fall through the cracks, either going without coverage or relying on the miserably malfunctioning individual, “non-group” insurance market.
