KFF’s analysis of the 2026 Voter Poll by SSRS shows midterm voters gave Democrats a 19-percentage-point advantage on which party is better able to handle health care. Voters also gave Democrats a narrow edge on handling the economy (43% vs. 37%), a reversal from 2024, when Trump had a 10-point advantage over Harris.

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.
