“…voters’ concerns about health care costs are having a moment, and will continue to do so through 2028, because voters see them as a dimension of their worries about the cost of living, which is their dominant concern right now.” — Drew Altman, KFF Founding President and CEO

From Drew Altman: A Guide to the Role of Health in the Midterms

In a new column, Founding President and CEO Dr. Drew Altman says health care costs are playing a significant role in the midterms as one dimension of voters’ concerns about cost of living, and explains why pollsters, analysts, and candidates should look at it that way, and not as a separate voting issue. He writes, “The ‘issue’ that matters most in this election is cost of living and the cost of health care is a central element of it for voters.”
