Politics is widening the health death gap in America

For years, Americans have argued about politics in dinner-table debates and election-night chaos. But a new study suggests the argument may be getting under the skin—showing up in biomarkers first, and then in deaths.

The research. published in Nature last month. examines individual health data from a long-term study of a large. representative sample of Americans across all 50 states. It finds that the health gap tied to political ideology has emerged over the past decade. leaving conservatives “less healthy than liberals” by 2020.

Elizabeth Elder, a coauthor of the study, puts a clear marker on the timeline. “2010 is the last year in which we can say fairly clearly that there is not this gap,” she says. “By 2020 we have pretty clear evidence of a gap in which conservatives are less healthy than liberals.”

The pattern becomes harder to ignore as the years progress. By 2016, the gap had begun to appear in biomarker measures. By 2020, it showed up in deaths from causes including heart disease, cancer, and stroke. Since then, the divide has only widened.

Between 2020 and 2022, the study reports a stark difference in internal-cause deaths: only 0.2% of “very liberal” respondents died of internal causes, compared with 1.34% of “very conservative” respondents.

The authors argue the divide cannot be dismissed as a side effect of COVID-19 deaths. demographic differences. geography. or the simple fact that some groups are older than others. Instead, they focus on a widening ideological divide in trust—specifically trust toward doctors and the broader medical system.

That mistrust, the study suggests, did not stay confined to politics online. During the COVID-19 pandemic, fights over masks and vaccines moved from social media into everyday life. Now the lack of trust appears to be spreading to other routine health decisions. from taking blood pressure medication to seeing a doctor for chest pains.

Elder describes the risk with a blunt warning: “We found that the gaps in trust and willingness to go to the doctor were no different for people with chronic health conditions than people without them.” She adds that for younger. healthier people. mistrust may not have immediate consequences. But for older people or those with chronic health conditions. she says. it could become “a matter of life and death.”.

The timing of the shift mirrors an increasingly politicized U.S. health landscape. The study frames the period after 2020 as one in which health in America has become more entangled with ideology. Under President Donald Trump, Robert F. Kennedy Jr. assumed the role of Secretary of the Department of Health and Human Services. and federal health policy has been reshaped by the “Make America Healthy Again” movement.

RFK Jr.’s antivaccination agenda has gained ground as more red states move to eliminate vaccine mandates. At the same time, MAHA and MAHA-adjacent wellness influencers have cast doubt on a wide range of health-related issues—from sunscreen to chemotherapy.

The roots of that skepticism run deep. A 2023 survey from the American Academy of Physician Associates found that nearly three out of four U.S. adults say the country’s medical system fails them in some way. The study points to how MAHA stalwarts have capitalized on that frustration to push an antiscience and antiestablishment political agenda.

Even so, Elder stresses that the health gap predates the MAHA movement, which gained traction in late 2024. Still. she says it is plausible MAHA helped broaden skepticism toward medicine beyond the COVID-19 pandemic—and that it could help sustain the widening divide in health outcomes between conservatives and liberals.

The most unsettling part may be how the evidence lands without requiring a single villain or a single cause. The study does not establish causation. But Elder draws a line that is impossible to miss: “What we can say is that health outcomes were not correlated with politics as of 2010. ” she says. “And they are correlated with politics now.”.

In the data. the shift shows up slowly—first in biomarkers by 2016. then in deaths by 2020. and finally in a widening gap between 2020 and 2022. In everyday life. it shows up as a growing willingness to question doctors and delay care. at exactly the moments when medical decisions are supposed to be least negotiable.
