Jonathan Weiner, professor in health policy at the Johns Hopkins Bloomberg School of Public Health, talks about the good and not-so-good aspects of the nation’s historic health insurance expansion, including the refusal of several states with Republican governors to accept federal funds to cover the poorest of their uninsured. Weiner calls that “the biggest political malpractice I’ve seen in my life.” A 30-minute look at the status of the law nationally and in Maryland with one of the country’s go-to experts on the law.
