Since the enactment of the Affordable Care Act (ACA) in 2010, the KFF Health Tracking Poll has provided routine measures of public opinion of the health care reform law. Public opinion on the ACA has shifted over the years, most notably following Republicans’ unsuccessful efforts to repeal it during the first Trump administration. While overall opinion of the ACA has been more favorable than unfavorable since 2017, there remain deep partisan divides. This page examines how specific groups feel about the law and how those opinions have changed or not changed over time. Access all KFF Health Tracking Poll resources here.
