What the Study Found
- 41% of U.S. adults support MAHA, a group mostly Republican and MAGA-aligned, but its concerns reach a wider public.
- Even among MAHA voters, lowering health care costs (42%) is the top priority—double food additives (21%), the next issue.
- Majorities say food additives (75%) and pesticides (64%) are under-regulated, cutting across party and MAHA lines.
- Voters give the Trump administration weak marks on vaccine (38%) and food policy (46%); even MAHA approval is tepid.
Ask the people who back Make America Healthy Again to name the one thing they most want the federal government to fix, and the answer is not what the movement has spent two years shouting about. It is not chemical additives. It is not pesticides, and it is not vaccines. It is the price of a doctor’s visit. Forty-two percent of MAHA movement voters pick lowering the cost of health care as their single most important priority, twice the share who name restricting chemical additives in food.
That number, from a recent KFF Health Tracking Poll, is the sort of finding that complicates a tidy political story. The concerns MAHA has elevated turn out to be real and widely shared. They are just not, for most voters, the thing that moves a ballot.
KFF, the health policy outfit whose tracking polls are about as close to a gold standard as US health opinion research gets, surveyed 1,343 adults in mid-April. Roughly four in ten of them, 41%, call themselves MAHA supporters, a group that leans heavily Republican and overlaps tidily with the MAGA coalition. But the survey’s more interesting move was to separate the movement’s branding from its supporters’ actual priorities, and then watch the two drift apart.
They drift a long way. Among MAHA voters, health costs beat additives by 21 points on the single-priority question, with vaccine safety (10%) and pesticides (8%) trailing far behind. The pattern holds regardless of party, too: MAHA Democrats, independents and Republicans all put cost first, each of them ranking it at least 14 points ahead of the additives question. So this is not one faction of the movement pulling the average around. It is the whole coalition, agreeing on the thing the movement talks about least.

The Worries Travel Further Than the Movement
Here is the part that should give both parties pause. Three-quarters of all adults, 75%, say there is not enough regulation of chemical additives in food. About two-thirds, 64%, say the same of pesticides. Those majorities hold across party lines and among people who want nothing to do with MAHA, which suggests the underlying anxiety is not partisan at all. It predates the movement and outreaches it.
Some of that unease seems rooted in a broader distrust of the companies and regulators involved. Only a quarter of adults trust food and beverage companies to act in the public’s interest, and barely a fifth, 21%, trust pharmaceutical firms. Confidence that the FDA or EPA can act independently sits at 36% apiece. Doctors, for what it’s worth, still clear seventy percent. The institutions have lost the room; the person with the stethoscope mostly hasn’t.
The respondents themselves put it plainly. “America uses far too much harmful ingredients that most other countries ban,” one 28-year-old independent man from Indiana told the pollsters, capturing a sentiment that shows up well outside the movement’s core. A 58-year-old Republican woman in Kentucky framed her support in almost fiscal terms, saying the point was to get people healthier so taxpayers would not have to foot the bill. Even sympathisers, in other words, keep circling back to cost.
A Signature Movement, Politely Applauded
There is a wrinkle for the administration in all this. Robert F. Kennedy Jr., the Health and Human Services Secretary who leads the MAHA Commission, is the face of these policies, and among MAHA voters his numbers look healthy on the surface: about 69% approve of how he is handling the job. Dig one layer down, though, and the enthusiasm thins. Only around a third of MAHA voters strongly approve of his performance, and a similar share actually disapprove. KFF’s own verdict was blunt, calling these “tepid ratings for a group that aligns with Kennedy’s signature movement.”
Broaden the frame to all voters and the picture cools further. Just 38% approve of the administration’s handling of vaccine policy; 46% approve on food. On vaccines specifically, Democrats hold a double-digit trust advantage, 41% to 25%. The childhood immunisation schedule changes made earlier this year appear to have cost the administration more than they gained.
None of this means the food and pesticide worries will fade. If anything, the poll hints they have detached from MAHA entirely and become a standing feature of how Americans feel about their food supply, available for whichever party fancies picking them up. There is a caveat that cuts against easy regulation, mind you: when told stricter rules might raise grocery prices, support for tougher additive regulation dropped 13 points, from 75% to 62%. Cost, again. It shadows every question in the survey, even the ones ostensibly about something else.
Which leaves an odd situation heading into November. A movement built on the promise of cleaner food and closer scrutiny of vaccines has succeeded in spreading its anxieties across the electorate, yet cannot get its own supporters to rank those anxieties first. The wallet keeps winning. Whether anyone campaigning on additives and immunisation has quite noticed is the question the autumn will answer.

Frequently Asked Questions
Do MAHA supporters actually care most about food additives and vaccines?
Not when forced to choose. In the KFF poll, 42% of MAHA-supporting voters named lowering health care costs as their single most important priority for the federal government, twice the 21% who picked restricting chemical additives. Vaccine safety and pesticides trailed at 10% and 8%. So while additives and vaccines define the movement’s brand, its own voters rank cost well above them.
Is concern about chemical additives just a MAHA thing?
No, and that is one of the poll’s central findings. Three-quarters of all US adults (75%) say there is not enough regulation of chemical additives in food, and 64% say the same about pesticides, with majorities holding across party lines and among people who do not support MAHA. The worry is broad and bipartisan, which means it exists largely independent of the movement that has publicised it.
How popular is Robert F. Kennedy Jr. with the movement he leads?
More lukewarm than the headline number suggests. Around 69% of MAHA voters approve of his handling of the HHS job, but only about a third strongly approve, and a similar share disapprove. KFF itself described these as tepid ratings for a group aligned with Kennedy’s signature movement.
Why do health care costs keep overshadowing everything else?
Because cost anxiety runs underneath nearly every question in the survey. More than half of voters say health costs will have a major impact on how they vote, well above the roughly four in ten who say the same of vaccine or food policy. Even support for stricter food regulation fell 13 points when respondents were told it might raise grocery prices, showing how quickly cost concerns override other priorities.
