With an estimated 14 million people expected to become uninsured by 2034 due to major changes to Medicaid and the Affordable Care Act (ACA) Marketplaces in the 2025 reconciliation law plus the expiration of the ACA’s enhanced premium tax credits, KFF’s new interactive maps provide a way to view ACA Marketplace and Medicaid enrollment by congressional district across the U.S.
This ACA Marketplace enrollment map shows that more than half of Marketplace enrollees (55%) live in Republican districts. The highest shares of state enrollment are in Florida (16%), Georgia (11%), Texas (10%), and Utah (10%)—states that were all won by President Trump in 2024.
This new interactive map illustrates Medicaid enrollment by congressional district and eligibility group. In half of Republican congressional districts, at least 20% of residents are enrolled in Medicaid, and in half of Democratic districts, at least 25% are enrolled.
As the 2026 midterms approach, health care costs remain tied with gas as voters’ top midterm concerns and the Democrats hold a clear edge over the Republicans Party on who voters trust to handle many top electoral issues, including the cost of health care and the cost of living.
These fact sheets offer background on election-related health care issues.
More people than ever got coverage through the Affordable Care Act Marketplaces in 2025, but the expiration of enhanced premium tax credits has driven up what people pay and contributed to declining enrollment in 2026.
Major federal changes to Medicaid eligibility and financing from the 2025 reconciliation law are coming, including new work requirements that will affect millions of Medicaid enrollees.
As health care costs dominate the national political conversation, our 2026 KFF Women’s Health Survey shows the toll those costs are taking on women. Our new nationally representative survey of women and men ages 18–64 finds costs remain a major barrier for women, specifically — causing everything from delayed care to rationed medications to cuts in spending on basic needs.
Health care affordability is a top issue for many people. Why and how did care get so expensive? In this three-part video series, KFF experts look at the rising cost of health care in the U.S. from the macro level to the issues facing everyday Americans. Drawing on KFF policy analysis and polling, the videos examine the underlying drivers of health care spending, the true cost of employer sponsored health insurance and whether the Affordable Care Act has delivered on its promise.

Political leaders on both sides point fingers at health insurers for high costs and patient frustrations. How much blame do insurers, in fact, deserve for our health system’s problems? This three-part video series from KFF considers this question and the complicated answer, exploring what’s driving rising insurance premiums, whether insurers provide value, and who we trust to decide what gets covered and at what price.
