Republican presidential nominee Mitt Romney’s plan to repeal the Affordable Care Act would result in about 72 million U.S. residents being uninsured in 2022, compared with about 27 million uninsured individuals under the Affordable Care Act, according to a report. The report estimated that the ACA will reduce the uninsured rate from 15% to 10% in 13 Southern and Western states, as well as New York and the District of Columbia. The ACA is projected to lower the uninsured rate to less than 10% in the remaining states, according to a posting at www.californiahealthline.org.
