Nine years after the Affordable Care Act was passed under the Obama administration, Americans are still more likely to support than oppose the law, 48% to 30%, according to an April poll from The Associated Press-NORC Center for Public Affairs Research , though a sizable share doesn’t take either side. Views of a single-payer health care system, in which all Americans would get their insurance from one government plan, are mixed: More Americans favor than oppose single-payer, 42% to 31%, and an additional 25% say they hold neither opinion. The public is even more supportive of a government health insurance plan that can be bought instead of a private insurance plan: 53% express support, compared with just 17% who oppose; 29% are neither in favor nor opposed.
