As the debate continues over repeal of the Affordable Care Act and what might replace it, a growing share of Americans believe that the federal government has a responsibility to make sure all Americans have health care coverage, according to a new Pew Research Center survey.Currently, 60% of Americans say the government should be responsible for ensuring health care coverage for all Americans, compared with 38% who say this should not be the government’s responsibility. The share saying it is the government’s responsibility has increased from 51% last year and now stands at its highest point in nearly a decade.
