Over the past two years, the constitutionality of President Barack Obama's health care overhaul has been powerful fodder for politicians and special interest groups.
But for most Americans, the decision by the Supreme Court, expected 10 a.m. EST Thursday, will have a very real impact.
If the law is struck down, those with a preexisting condition may be kept from getting health insurance. Kids under the age of 26 may be taken off of their parents' health care plan. And businesses may soon see higher insurance costs.
If the law is upheld, many Americans may worry that Congress really will tell us to eat our broccoli. Many small businesses, free of uncertainty, may take steps to hire and grow.
