The Commonwealth Fund predicted the number of uninsured would be 72 million by 2022, Politico reported. The report said if Congress had not passed President Obama's Affordable Care Act 60 million people would have had no health insurance by then and 27 million would be uninsured under the ACA.
Obama's healthcare plan was based on the law Romney, the Republican presidential nominee, enacted as governor of Massachusetts. But Romney has said he would repeal the federal law, replacing it with a system of Health Savings Accounts that would be used to buy private insurance coverage.
Under the Romney plan, more than a quarter of non-elderly U.S. residents would be uninsured by 2022, the Commonwealth Fund said. The report predicted the uninsured would be more likely to live in the South and West.
Ryan Williams, a Romney spokesman, called the report "flawed."
"The American people did not want this law, our country cannot afford this law, and when Mitt Romney becomes president he will repeal it and replace it with common-sense, patient-centered reforms that strengthen our healthcare system," Williams said.
