In the link you sent, it says "CBO now estimates, on the basis of an analysis incorporating the results of recent research, that if a package of proposals ... was enacted, it would reduce total national health care spending by about 0.5 percent (about $11 billion in 2009)"
but like I said before, tort reform will get passed, but it will be a totally different bill. so stop bitching about it.
then the private insurers have nothing to fear. (and if they have nothing to fear ... why are they fighting it so strongly?)
