I'm not sure what funding cap you're referring to, or what it would apply to. Elaborate?
Note that Obama has decreed that he will only accept health care reform that is budget-neutral, so whatever money is need to pay for the things in it has to be supplied by other parts of the health care reform legislation (be it taxes, fees, savings, funding shifts, whatever). So the total net spending on the reform is supposed to be 0, and all versions of the legislation aim for that, though perhaps with different means and using different projections. Talking about a "funding cap" for the whole thing therefore doesn't seem to make sense.
