Health care costs move to the center of the midterm electorate

Health care affordability has become a kitchen-table issue with electoral force. In KFF’s preelection polling, 60% of registered voters said they were worried about paying for health care for themselves and their families, putting the issue alongside gasoline and transportation costs at 59% near the top of voter money worries before the Nov. 3 midterm elections. In a campaign season crowded with inflation, taxes, and partisan grievance, the price of seeing a clinician, filling a prescription, or covering a hospital bill landed squarely in the same category as the everyday costs families feel most immediately.

The poll surveyed 1,328 U.S. adults, including 1,013 registered voters, from Sept. 16-21, 2026, online and by telephone in English and Spanish. The margin of sampling error was plus or minus 3 percentage points for all adults and plus or minus 4 points for voters.

A big health care bill is the least predictable expense in the household budget.

That unpredictability explains why health care keeps rising in salience even when broader inflation eases. Food and gas prices are visible at the checkout counter or pump; medical bills often arrive later, larger than expected, and with less transparency. For patients, the concern is not abstract policy design. It is whether a deductible, copay, premium increase, or uncovered service will force a delay in treatment or a hard choice between care and other essentials.

Democrats hold a widening trust advantage on costs

The political penalty for high prices is landing unevenly. Forty-two percent of voters said they trust Democrats to do a better job handling the cost of health care, compared with 22% who chose Republicans. Another 28% trusted neither party and 8% trusted both equally. The 20-point gap has grown from 11 points when KFF asked the same question in October 2020, when Democrats led Republicans 37% to 26%.

The pattern extends beyond health care. Democrats also held an edge on the cost of living, abortion policy, and the conflict with Iran, while Republicans ran closer on immigration and fraud in government programs. Among independent voters, 38% trusted Democrats on health care costs and 9% trusted Republicans, while 43% trusted neither party. That leaves a large block of the electorate skeptical of both parties but still leaning toward Democrats on the issue that is most likely to touch a family’s finances directly.

Eighty-two percent of voters said it is very or extremely important for candidates to discuss health care costs in the final weeks of the campaign, and 47% said it is extremely important. Only the cost of living ranked higher on the list of concerns, with 62% calling it extremely important. Democrats and independents were far more likely than Republicans to say the issue belongs near the top of the campaign agenda.

Voters want relief, not rhetoric

When voters were asked in their own words what they want to hear from candidates on health care costs, the answer was simple: a plan to bring those costs down. Ashley Kirzinger, KFF’s director of survey methodology, said that when KFF asks people what they want to hear from candidates on health care, the answer is a plan to bring costs down. The consistency of that message matters more than the finer points of party branding. Voters are asking for price relief, and they are asking it in plain language.

That demand for practical relief helps explain the broad appetite for change in the health system itself. Thirty-six percent of adults said the U.S. health care system has so much wrong with it that it needs a complete overhaul, and another 49% said it has some good things but needs major changes. Those views cut across party lines: 89% of Democrats and 77% of Republicans said the system needs either an overhaul or major changes. Only 10% of Democrats and independents said it needs only minor changes, compared with 21% of Republicans.

Medicare for All support rises and falls with framing

Public support for a national government health plan, often called Medicare for All, reached 66% among U.S. adults, the highest share KFF has recorded since it began asking about the idea in 2016. The figure was up from 53% when the question was last asked in October 2020. Support was strongest among Democrats at 84% and independents at 72%, while 66% of Republicans opposed the idea, including 48% who strongly opposed it. Younger adults were more supportive than older adults, with 75% of those ages 18 to 29 in favor compared with 54% of adults 65 and older.

The numbers moved sharply when respondents heard arguments for and against the policy. Support fell to 24% when people were told a national plan could lead to delays in some medical tests and treatments. It dropped to 35% when told most Americans would pay more in taxes, and to 38% when told it would threaten the current Medicare program. Support rose to 76% when respondents heard it would guarantee health insurance as a right for all Americans and to 75% when told it would eliminate premiums and reduce out-of-pocket costs for most Americans.

This is the central tension in American health reform. The same policy can be framed as universal protection or as a threat to access, taxes, and existing coverage. Public opinion does not sit still; it shifts with the cost argument attached to the plan. In practice, voters appear to favor coverage expansion when they hear lower personal spending and dislike it when they hear disruption, waiting, or tax burdens.

The question of eliminating private health insurance companies was nearly split down the middle, with 52% in favor and 47% opposed. In October 2020, the balance ran the other way, with 37% in favor and 58% opposed. The movement suggests a public more open to structural change than it was six years ago, but still vulnerable to counterarguments about transition costs and service delays.

The policy fight has already reached the campaign trail

That debate is not theoretical. Democratic Senate candidates in Maine, Minnesota, and Florida have campaigned on replacing the current insurance system with broad Medicare coverage. In Michigan, the issue has become central to the Senate contest between Democratic nominee Abdul El-Sayed, M.D., who trained as a physician and served as Detroit’s top public health official, and Republican Mike Rogers, a former Michigan congressman. Rogers has argued that millions of Michiganders with private insurance would lose coverage under Medicare for All and has pointed to estimates of roughly $4 trillion a year in costs.

A preprint study from Yale researchers estimated implementation at $4.2 trillion and projected about $1 trillion in savings on health care spending. Jonathan Oberlander, Ph.D., a health policy scholar at the University of North Carolina at Chapel Hill, said even with an El-Sayed win, the odds of Medicare for All replacing the current system remain very remote in the short to medium term.

Organized medicine still favors guarded reform

Physician organizations have been split, cautious, or openly opposed depending on the model. In 2020, the American College of Physicians endorsed either a single-payer system or a public option alongside regulated private insurance as paths to universal coverage in policy papers published in Annals of Internal Medicine. The college also warned that adopting single payer would be highly disruptive and could import price controls that repeat Medicare’s longstanding undervaluation of primary care. Under either model, the ACP said physician payments must be high enough to preserve patient access.

The American Medical Association’s House of Delegates declined in 2019 to drop its long-standing opposition to a single-payer system and instead backed proposals to strengthen the Affordable Care Act. Those positions frame the fault line now visible in the electorate: broad support for lower out-of-pocket costs and coverage expansion, paired with real anxiety about how a new system would affect access, waiting, physician payment, and existing coverage.

The political momentum is real, but the policy test remains steep: prove that lower bills will not come at the expense of access, timing, or the coverage patients already have.
