"The Congressional Budget Office, in an email to Capitol Hill staffers has said that repealing the national health care law would reduce net spending by $540 billion in the ten year period from 2012 through 2021. That number represents the cost of the new provisions, minus Medicare cuts. Repealing the bill would also eliminate $770 billion in taxes. It's the tax hikes in the health care law (along with the Medicare cuts) which accounts for the $230 billion in deficit reduction." http://spectator.org/blog/2011/01/07/breaking-cbo-says-repealing-ob
