As the Supreme Court hears cases challenging the constitutionality of parts of the Affordable Care Act, a relatively small share of the public thinks the Supreme Court’s decision will have a lot of impact on their family (28 percent). At the same time, the public is divided as to whether the law overall will leave their own families better off (26 percent), worse off (33 percent), or if it won’t make much difference (34 percent). Because certain groups of the population, such as the uninsured and those with modest incomes, stand to benefit more than others from the law’s provisions, particularly the Medicaid expansion and subsidies to purchase coverage, a new Data Note examines people’s impressions of how the law and the Court case will affect them, focusing primarily on those groups that are in the position to receive the greatest benefits.
