http://www.politifact.com/truth-o-m...romney-says-obamacare-adds-trillions-deficit/ How is it that a law can raise taxes and cut spending, but also add trillions to the deficit? That was Mitt Romneys claim after the U.S. Supreme Court upheld the core of the health care law on June 28, 2012. "Obamacare raises taxes on the American people by approximately $500 billion. Obamacare cuts Medicare -- cuts Medicare by approximately $500 billion," Romney said. "And even with those cuts and tax increases, Obamacare adds trillions to our deficits and to our national debt, and pushes those obligations on to coming generations." Here, were fact-checking Romneys claim that "Obamacare adds trillions to our deficits and to our national debt." Its a topic weve researched before. We asked the Romney campaign for their evidence for this statement, but we didnt hear back. For claims about laws that are not yet fully enacted, our go-to source is the Congressional Budget Office. Its a nonpartisan, widely respected agency with an expert staff that generates projections and reports about how proposed laws affect the federal budget. The Congressional Budget Office is not always right in its projections. In recent years, for example, it overestimated how much it would cost to cover prescription drugs for seniors in Medicare. The program actually came in under projections. But for claims about deficits, we consider the Congressional Budget Office, often called the CBO, to be the standard by which we fact-check claims. The CBO said this about the health care law back in 2010: It lowers the deficit, by about $124 billion over 10 years. More to read in the article.
