A new study to be released Tuesday says that President Obama’s health-care law will add $340 billion to the national deficit over the next decade. The study stands in direct opposition with the administration’s claim that the bill, which the White House claims will cut Medicare payments, will save the country money in the long run. The study was directed by conservative policy analyst Charles Blahous, who oversees Medicare financing. He was appointed by Obama in 2010 as a public trustee for Medicare and Social Security. “Does the health-care act worsen the deficit? The answer, I think, is clearly that it does,” Blahous said.
