SACRAMENTO (AP) — A national health policy nonprofit on Thursday announced it is making California the focal point of a long-term research project to examine whether the Affordable Care Act lives up to expectations for the uninsured. The Kaiser Family Foundation released the initial results of interviews with 2,000 randomly selected Californians who had lacked health insurance for at least two months. The study will follow the respondents for two years, as they examine their options under the federal health care law.
