Midterm Election Update: The Affordable Care Act Marketplaces Published: Oct 6, 2026

Law and regulatory changes also tightened ACA eligibility and enrollment requirements, including for some lawfully present immigrants. Public opinion of the ACA remains generally favorable, although views remain divided along partisan lines.
