Supporters slow to grasp health law's legal risks

With the Supreme Court likely to render judgment on President Obama's healthcare law this week, the White House and Congress find themselves in a position that many advocates of the legislation once considered almost unimaginable. In passing the law two years ago, Democrats entertained little doubt that it was constitutional. The White House held a conference call to tell reporters that any legal challenge, as one Obama aide put it, "will eventually fail and shouldn't be given too much credence in the press." Congress held no hearing on the plan's constitutionality until nearly a year after it was signed into law.
