Americans’ approval of the Affordable Care Act (ACA) continues to edge downward from its record-high 55% in April 2017, when congressional Republicans first attempted to dismantle it. The public is now about evenly divided in their opinions of the 2010 healthcare law, with 48% approving and 47% disapproving.

Americans’ opinions of the ACA have fluctuated over the past six years, but before April 2017, as congressional Republicans were attempting to dismantle it, an average 43% of Americans approved of it and 51% disapproved. The April and July 2017 readings were the only times Gallup has measured approval at the majority level, and by November 2017, approval had slipped to 50%.
