"The health care plan Obama offered as a candidate would have cost nearly $1.2 trillion over ten years, according to a detailed estimate last fall by the Lewin Group, a leading consulting and policy analysis firm. The campaign plan would not have covered all the uninsured, as most Democrats in Congress want to do. But it is a starting point for lawmakers."
"John Sheils, a senior vice president of the Lewin Group, said about $1.5 trillion to $1.7 trillion would be a credible estimate for a plan that commits the nation to covering all its citizens. That would amount to around 4 percent of projected health care costs over the next 10 years, he added."
