This means further reducing health care costs, including programs like Medicare and Medicaid, which are the single biggest contributor to our long-term deficit. The health insurance law we passed last year will slow these rising costs, which is part of the reason that nonpartisan economists have said that repealing the health care law would add a quarter of a trillion dollars to our deficit. Still, I'm willing to look at other ideas to bring down costs, including one that Republicans suggested last year: medical malpractice reform to rein in frivolous lawsuits.
