Independently re-verified. As President (2021-2025) Biden actively led and signed two landmark laws that built directly on the ACA to lower costs: the American Rescue Plan (2021) enhanced ACA premium tax credits (average ~$800/year premium savings) and drove Marketplace enrollment from 11.4M (2020) to a record 24.3M (2025), and the Inflation Reduction Act (2022) extended those subsidies, capped Medicare insulin at $35/month, capped Medicare out-of-pocket drug costs, and granted Medicare first-ever drug-negotiation authority (first 10 drugs negotiated at 38-79% off list, ~$6B/year projected savings). These are independently corroborated by KFF, the Joint Economic Committee, The Hill, the Center for Medicare Advocacy, and CMS. CHAMPIONED (not FULL) is correct and fair: premiums and drug prices were verifiably lowered through enacted legislation he led, but deductible relief was indirect (limited to cost-sharing reductions for some enrollees), the enhanced subsidies were temporary (sunset Dec 31, 2025), and no public option was enacted. The same standard applied to any party's president who championed and signed comparable cost-lowering legislation would yield CHAMPIONED. The cited CMS fact sheet returned HTTP 403 to automated fetch (bot-block), but its content and URL pattern are corroborated by parallel CMS results and multiple independent sources; at least three real supporting sources substantiate the outcome. Rating stands.
