With the 2026 midterms about a month away, 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. Two-thirds of U.S. adults now favor Medicare-for-all, a new high in KFF Polling, but support shifts when competing claims from critics and proponents are heard.

RSVP for a virtual event featuring KFF public opinion experts providing insights on the latest polling about health care issues in advance of the midterms, including current public sentiment about Medicare-for-All. After the presentation, experts will take questions from attendees.

The latest KFF Tracking Poll on Health Information and Trust finds about half of parents mistakenly believe spacing out vaccines is healthier for children, while confidence in many long-standing childhood vaccines is high across partisans. These findings take on new relevance following President Trump’s recent executive order calling for changes in U.S. childhood vaccine recommendations, including splitting the measles, mumps, and rubella (MMR) vaccine—currently given as a single combined shot—into three separate vaccines across multiple visits.

Drawing on KFF’s poll findings, this interactive dashboard tracks the public’s trusted sources for health information, attitudes toward vaccines, and use of news, social media, and AI for health-related information.
