About one in 10 Americans -- 9% -- say The Affordable Care Act has improved their health insurance situation in the past year, according to a new survey by Bankrate.com. The telephone survey asked a representative sample of 1,001 Americans about their knowledge of and feelings about the law that mandates health care insurances for all Americans in coming years. The survey was conducted from Oct. 17 to 20 after a 16-day federal government shutdown over raising the debt limit ended and the bungled launching of health exchange websites nationwide.
