Age-adjusted mortality 19.2% higher in 2024 Trump-voting states than Harris-voting states

The STAT News analysis of CDC mortality data shows the political mortality divide grew from a 2% gap in 2001 to 16.1% by 2019, driven by slower mortality declines in Republican-leaning counties. From 2016 to 2024 heart disease mortality fell only 2.9% in Trump states versus 9.1% in Harris states, while cancer mortality declined 9.1% versus 12.9%. These trends persisted after COVID peaks and align with non-expansion of Medicaid in the ten Trump states that have refused it.

Drug overdose patterns reversed: rates were initially higher in Trump states but fell below Harris-state levels by 2023, reflecting earlier peaks in 2021. This divergence points to differences in chronic disease management and healthcare access rather than a single pandemic effect. Observational county-level studies have linked Medicaid expansion to mortality reductions of 2-3% in expansion states, suggesting policy variation contributes to the measured gap.

Less affluent rural areas concentrated in non-expansion states show persistently lower rates of preventive screening and specialist access. The MAHA agenda's emphasis on lifestyle factors will need to address these structural barriers if the mortality trajectory is to converge. Next steps require state-level linkage of claims data to mortality files to isolate insurance status from behavioral and environmental contributors.
