Congressional Budget Office analysts have given House leaders cost estimates for two competing versions of their plan to overhaul the healthcare system, concluding that one comes within striking distance of the $900 billion limit set by President Obama and the other falls below it. The report from the CBO puts the cost of one plan at $859 billion over the next decade and the other at $905 billion. The cheaper version would rely heavily on a more dramatic expansion of Medicaid, reports the Washington Post.
