Even as well being care points rise in the 2026 marketing campaign debate, new knowledge present that much more House Republicans than Democrats symbolize districts the place probably the most residents face main medical challenges — and lack medical health insurance.
An unique NCS evaluation of information collected by the Congressional District Health Dashboard project finds that considerably extra House Republicans than Democrats maintain seats the place an elevated proportion of residents are experiencing such vital well being issues as diabetes, hypertension, weight problems, and deaths from cardiovascular issues or breast most cancers. Likewise, many extra House Republicans than Democrats now symbolize districts the place the share of residents who’re uninsured exceeds the nationwide common.
In a robust measure that crystallizes all these disparities, outcomes from the dashboard present that just about 70% of House Democrats symbolize districts the place life expectancy now exceeds the nationwide common — whereas life expectancy lags under the nationwide common in over 70% of Republican seats.
These stark disparities present a dramatic backdrop for the escalating marketing campaign confrontations over well being care. In their 2026 messaging, Democrats and their allied teams are aggressively condemning the Republican strikes final yr to cut Medicaid in the “One Big Beautiful Bill” and to permit the expiration of enhanced subsidies beneath the Affordable Care Act.
Polls constantly present that almost all Americans oppose these well being care cuts. The paradox is that concern about well being care could assist Democrats extra in swing districts which are much less instantly affected by the GOP cuts than in the seats that face probably the most direct impacts.
Many of the GOP districts with the worst well being outcomes and the bottom ranges of medical health insurance are predominantly White, culturally conservative rural locations, typically in the South. In most of these districts, President Donald Trump gained overwhelming majorities in 2024, and Democrats have struggled to compete in any respect.
Michael Shepherd, assistant professor on the University of Michigan college of public well being, and author of an upcoming book “Rural Pain, Republican Gain,” says his analysis reveals that deteriorating well being outcomes seem to have strengthened the GOP in small cities and rural communities experiencing them. “Those worse outcomes lead those White voters to blame the Democratic Party for their bad health, in part because they are blaming the government vaguely and they associate the Democratic Party with government,” he says.
No longer the ‘wealthy and healthy party’
The Congressional District Health Dashboard is a partnership between the New York University Grossman School of Medicine and the Robert Wood Johnson Foundation. The venture uses federal data from the Census Bureau; the Centers for Disease Control and Prevention; the National Center for Health Statistics; and different sources to calculate whether or not every congressional district ranks above or under the common for all districts nationwide on 40 totally different metrics of well being standing. The NYU researchers up to date most of the measures this spring with the latest accessible knowledge.

The dashboard’s newest outcomes replicate the district traces that have been used in the 2024 election. Ben Spoer, program director of the Congressional District Health Dashboard, says the analysts count on that by subsequent March they’ll replace most of the measures to replicate the brand new districts created by the waves of gerrymandering in latest months.
The newest outcomes vividly seize the class inversion that has reshaped every celebration’s coalition over roughly the previous half century. In the House, Democrats now rely totally on an upstairs-downstairs coalition of seats that revolve round college-educated suburban voters of all races and concrete districts dominated by extra economically struggling racial minorities. Republicans in the meantime maintain far fewer House seats than they as soon as did in prosperous suburban areas and as an alternative rely totally on exurban, small-town and rural seats with massive populations of economically squeezed White voters with no four-year faculty diploma.
As the GOP’s electoral coalition has developed, “the health composition of the Republican Party has shifted from being the ‘wealthy and healthy party’ to, at least in terms of white Americans, (representing) some of the worst health observed in the country,” says Shepherd.
Consistently throughout the measures that the dashboard tracks, extra Republicans than Democrats maintain seats the place the share of residents confronting severe well being issues exceeds the nationwide common. That sample holds for hypertension, weight problems, deaths from breast and colorectal most cancers, cardiovascular deaths, diabetes, teen births and firearm suicides, amongst different issues. (Somewhat surprisingly, elevated ranges of opioid overdoses are barely extra widespread in Democratic than Republican districts). Looming over all these developments is the disparity in medical health insurance: 54% of House Republicans, in comparison with simply 31% of House Democrats, maintain seats the place the share of uninsured folks is increased than the nationwide share.
“What you really don’t want to see is a situation where there’s a greater prevalence of chronic conditions in places that have even lower than average insurance coverage because the implications of that for prevention and management are dire,” says Marc Gourevitch, a professor of inhabitants well being on the NYU medical college and co-principal investigator for the dashboard.
Joseph Antos, a senior fellow emeritus on the conservative American Enterprise Institute, says these disparities will not be shocking given the shifting nature of the voters both sides now primarily represents.
Republican districts now “skew blue collar and rural, so residents are more likely to have physically demanding jobs, they may be more exposed to greater health risks (related to occupation, environment — think coal and steel industries, for example),” Antos mentioned in an e mail. “Rural areas don’t have major medical centers by and large, and it can be difficult to get even basic health care.” Further, Antos notes, rural residents are “less likely to have health insurance.”
Jennifer Karas Montez, a Syracuse University sociologist who research US life expectancy, factors additionally to diverging coverage selections between blue and crimson states. (Both events now depend on the states that lean most reliably towards them in presidential elections for about two-thirds of their House members.) She notes that revenue assist for low-income households, well being care protection, vaccine acceptance, and measures to discourage smoking and firearm violence are all way more prevalent in blue than crimson states, whereas Democratic-leaning metro areas additionally are likely to have extra public facilities than red-leaning smaller communities.
“What’s been happening over the last 40-50 years is that any given place tends to either have all the things that extend our lives, or all the things that cut our lives short,” she mentioned in an e mail.
Among Whites, the hole between Republican and Democratic districts is even bigger than it’s for all residents on a number of measures, together with firearm homicides and each teen births and low birthweight births. The common share of White residents who lack medical health insurance is sort of 50% increased in crimson than blue districts.
Nonetheless, each House Republican voted for the reconciliation invoice final summer time that imposed the largest cuts ever on the Medicaid program. The GOP Congress final yr additionally refused to increase the improved subsidies for the ACA that Democrats had accepted beneath President Joe Biden. In a recent study analyzing federal data, Protect our Care, a liberal well being care advocacy group, discovered that whole enrollment in the 2 applications has already declined by 5 million since June 2025.
Democrats hope to make the well being care cuts a central plank in their case that Republicans have compounded the affordability downside that Trump pledged to resolve. But the districts Democrats are focusing on this yr embrace virtually not one of the principally Southern seats with absolutely the largest variety of uninsured, in accordance with the NYU knowledge.
Larry Levitt, govt vp for coverage for KFF, a non-partisan well being care thinktank, says that doesn’t shock him. While uninsured folks could assist federal well being care spending in the summary Levitt says, KFF’s polling reveals that when “Republican leaders and President Trump are calling for (cuts) Republican voters are going to follow. It really depends on how things are framed.”
By distinction, the swing, closely blue-collar districts in states together with Pennsylvania, Michigan, Wisconsin, Iowa and Ohio the place Democrats are stressing well being care points are typically locations the place the variety of uninsured runs at, and even barely under, the nationwide common of round 10%.
In these districts, voters in all probability see the Medicaid and ACA cuts much less as a private menace than as a logo of misplaced GOP priorities and a failure to deal with their anxieties over value and protection, political strategists say. Even “a lot of people who aren’t on these programs” fear in regards to the affect of the cuts on their means to afford care, says Leslie Dach, founder and chair of Protect Our Care. “You can’t underestimate the strain that people have” about affording well being care, he says.
Whatever the affect of the GOP cuts in swing districts, the dearth of debate over them in the deep crimson seats the place their affect is best extends a protracted sample, Shepherd says. In his upcoming e book he presents proof that rural areas struggling by damaging well being trends-a hospital shutdown, or a spike in opioid or firearm deaths-tend to shift additional towards Republicans. That’s despite the fact that these issues, he notes, are routinely exacerbated by GOP well being care cuts on the federal degree, or a state refusal to increase Medicaid eligibility — and may be ameliorated by Democratic proposals to extend protection.
The tendency in these locations responsible Democrats, because the perceived celebration of presidency, for unfavourable well being occasions, Shepherd says, “creates what I call the rural health spiral: bad health outcomes lead to more Republican voting, and more Republican voting leads to policies that makes the health care outcomes even worse.”
Experts agree the most effective measure of the hardening well being divide is the distinction in life expectancy between crimson and blue districts. “It’s a very powerful summary measure of health that reflects the totality of the exposures good and bad that people have along their life course,” says NYU’s Gourevitch.
On common, residents in blue districts can count on to live 79.9 years, about two years longer than the 77.7-year common lifespan in crimson districts. To put that distinction into context, Karas Montez says it usually requires “over a decade of progress” for international locations to lift their life expectancy degree by two years. “So that means Republican-held districts have fallen over a decade behind Democratic districts,” she mentioned.
But the congressional district life expectancy hole is even better on the extremes of the size. The district with the best life expectancy, at 86 years, is the Manhattan seat held by retiring Democrat Jerrold Nadler. Democrats maintain every of the following 15 seats the place folks live longest. In all, Democrats maintain 81 of the 100 seats with the best common life span.
The district with the bottom life expectancy, at 71 years, is the agricultural Kentucky seat held by Republican Hal Rogers. The subsequent 15 lowest seats are cut up between rural Republican seats and closely African American Southern seats held by Democrats (a few of which have been eradicated in the latest redistricting.) But in all, Republicans maintain 73 of the 100 seats the place life expectancy is the shortest.
Looking solely at Whites, the events are sorted even additional: Democrats maintain 84 of the 100 seats the place Whites live longest and Republicans maintain 83 of the 100 the place they die soonest.
The sizable gaps between districts on the prime and backside of the US life expectancy ladder are corresponding to the variations often discovered between “countries at quite different levels of development or poverty,” says Gourevitch. Indeed, the 15-year distinction between life expectancy for all residents between the Nadler and Rogers seats roughly equals the lifespan hole between countries as far apart on the development ladder as Japan and Yemen, or Sweden and Senegal.
After dipping throughout COVID, common lifespans for the US nationwide improved in 2022 and 2023, according to federal data. But Shepherd says that as long as Republicans face no electoral penalties for advancing insurance policies that intensify the well being challenges in lower-income rural districts, the life expectancy hole between crimson and blue America is prone to proceed widening.
Karas Montez agrees. “Gaps in life expectancy between counties, states, and regions of the county have been widening since the early 1980s and show no signs of slowing down,” she mentioned.
Narrowing these gaps would enhance the US’s total life expectancy (which ranks behind about 60 other countries) and, by definition, would imply the nation was making progress in opposition to many different well being challenges. “Moving the needle on life expectancy means we will have potentially moved the needle on a lot of other things that we as a nation care about,” says NYU’s Spoer.
Health care may play a significant position in the marketing campaign dialogue this fall in the swing districts prone to resolve management of the House. But there’s virtually no probability the events will debate probably the most elementary difficulty of all, notably in the ruby crimson locations the place it’s usually most acute: Why are so many Americans, particularly in comparison with different industrialized international locations, dying earlier than their time?
