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.
