What Changes the MAGA Mind

Fact-checks bounce off. Broken promises, grocery bills, and a conversation without contempt do not. The evidence runs from Washington to Winnisquam.

Marjorie Taylor Greene spent five years as the loudest voice in Donald Trump’s chorus. On January 5 she walked out of Congress two years early, after the president she campaigned for branded her a “traitor” and promised to bury her in a primary. In her resignation video she said she refused to be a “battered wife” waiting for things to improve. Then she left the movement she helped build.

Nobody fact-checked her out of it. What moved her is what moves the smaller but real stream of voters now walking the same road: a promise broken on the movement’s own terms, a bill that lands on your own kitchen table, and an exit that does not require crawling. Those are the three levers. Persuasion researchers have documented them for a decade. The past twelve months demonstrated them in public, and New Hampshire is where the demonstration gets local.

What does not work is the thing almost everyone keeps doing: winning the argument.

The facts don’t do it

In 2010, political scientists Brendan Nyhan and Jason Reifler published the famous “backfire” finding, in which corrections sometimes left misperceptions stronger than before. Later work softened that scare. A large 2019 study by Thomas Wood and Ethan Porter in Political Behavior found backfire is rare; corrections usually nudge beliefs toward the truth. The catch came in Nyhan’s 2021 review for the Proceedings of the National Academy of Sciences: the nudge fades fast, and it gets drowned out by louder voices the person trusts. A companion 2019 study by Nyhan, Porter, Reifler and Wood found that fact-checks about Donald Trump changed what his voters believed and changed nothing about whether they supported him.

The reason is not stupidity. For a committed supporter, the contested claim is not a data point. It is a membership card. Attack the card and you are attacking the person’s people, their church parking lot, their deer camp, their family text thread. Nobody trades their people for your PDF. Which raises the working question of American politics in 2026: if information does not move the MAGA mind, what does? Three things showed up on the record over the past year, each with receipts.

Betrayal, on the movement’s own terms

Start with the promise. Trump campaigned on releasing the Jeffrey Epstein files. In July 2025 his own Justice Department and FBI closed the case instead, announcing there was no client list, that Epstein died by suicide, and that nothing more was coming. A Quinnipiac University poll taken the following week found 17 percent of voters approved of the administration’s handling of the files and 63 percent disapproved. The number that mattered sat in the crosstabs: Republicans split 40 percent approve, 36 disapprove, in a party that gives Trump marks near 90 on almost everything else.

The revolt that followed did not come from the left. Republican Thomas Massie and Democrat Ro Khanna forced a House vote through a discharge petition. Greene was one of only four Republicans to sign it. On November 18 the House voted 427 to 1 to release the files, the Senate passed the bill without a single objection, and on November 19 Trump signed the Epstein Files Transparency Act he had spent months deriding as a hoax. A week before the vote he pulled his endorsement of Greene. Days later she announced her resignation, effective January 5.

Here is the part an honest account has to print. Most of the base bent, then snapped back. Reuters/Ipsos polling in December found Republican approval of Trump’s handling of the Epstein matter climbed from 44 percent to 53 after he signed the bill, and CBS News/YouGov surveys showed the share of Republicans who said the files mattered to their view of Trump fell from 46 percent in July to 36 by November, a shift CNN’s polling analysts documented in detail. Identity absorbed the shock. What identity could not absorb were the people who took the promise literally. Betrayal does not move the tribal. It moves the sincere, and the sincere included the movement’s loudest congresswoman.

In New Hampshire, the sincere were most of the state. The UNH Survey Center’s August 2025 Granite State Poll found a bipartisan majority of Granite Staters wanted the Epstein documents released, months before Washington got around to it.

The kitchen table

The second lever is cost, and 2026 has run the experiment at full scale. This month’s CNBC All-America Economic Survey put Trump’s overall approval at 40 percent, with 59 disapproving, and his economic rating at the worst of his political career in that poll: 38 approve, 60 disapprove, with 61 percent of voters pessimistic about where the economy is headed. The June NPR/PBS News/Marist poll measured his approval at 36 percent, the lowest of his second term, with 17 percent of his own party’s voters disapproving.

The collapse is steepest among the voters who handed him his 2024 margin: the young. Economist/YouGov tracking, as reported by Newsweek, shows Trump’s net approval among 18-to-29-year-olds falling from plus 5 in January 2025 to minus 45 by late June 2026, a fifty-point slide. The Yale Youth Poll this spring found 68 percent of voters aged 18 to 22 and 72 percent of those 23 to 29 disapprove of his performance, and their top voting issue, chosen by 84 percent, is cost of living. I wrote a book, Generational Malpractice, about what happens when a country bills its young for its elders’ comfort. The 2026 polling reads like a chapter of it, and so does the state’s own math on young workers priced out of New Hampshire.

The Granite State numbers track the national ones. In April, six in ten New Hampshire residents disapproved of Trump’s job performance and fewer than a third said the country is headed in the right direction, per the UNH Survey Center. By late June the same pollsters reported his approval still eroding, with his foreign-policy rating at the lowest point of either term.

The steepest defection: Trump’s net approval among voters under 30, January 2025 to June 2026, per Economist/YouGov tracking reported by Newsweek. Chart: Granite State Report.

And the bill is not abstract here. Canadian visits to New Hampshire fell roughly 30 percent last summer by the state’s own estimate, and the hangover is shaping this one: NHPR reported this month that gas hit $4.49 a gallon in May, about 40 percent above a year earlier per AAA, that inflation is holding at 3.8 percent, and that a Lake Winnisquam resort is handing out gas cards to coax families north. In Meredith, the Nutmeg Inn told NHPR its revenue dropped 15 percent as Canadian bookings dried up and tariff-driven supply costs squeezed the other side of the ledger. Hampton Beach innkeepers watched Canadian guests, once half the business at some properties, all but vanish. Lakes Region readers do not need a pollster to explain any of this.

But cost alone does not finish the job, and pretending it does is its own kind of malpractice. Bradley Bartell, a Wisconsin Trump voter, watched federal agents detain his wife at the airport on the way home from their honeymoon and still told Newsweek, “I don’t regret the vote.” Wayne DeMario, a Miami-Dade small-business owner whose partner of twenty years was shackled at a routine immigration check-in, told Local 10 News he is done with the party: “I didn’t vote for this, but I definitely voted Republican.” Same policy. Comparable pain. Opposite verdicts. The difference is whether a man can still tell himself the deal he voted for is the deal he got. UNH’s February polling caught that double-mindedness in a single frame: Granite Staters are unhappy with ICE and still call illegal immigration a serious problem. Pain opens the door. It does not walk anyone through it.

The knock on the door

The third lever is the only one with randomized trials behind it: the conversation. In 2016, political scientists David Broockman and Joshua Kalla published a field experiment in Science on “deep canvassing” in Miami. A single ten-minute doorstep conversation about transgender people, built on listening and trading personal stories rather than reciting talking points, moved about one voter in ten. The change held for at least three months, survived attack ads, and worked on Republicans and Democrats alike. The researchers measured an attitude shift comparable to fourteen years of national change, produced in ten minutes at a stranger’s door.

Their 2020 follow-up in the American Political Science Review is the finding that belongs stapled to every canvassing packet in this state. Across three field experiments, 230 canvassers talked with 6,869 voters in seven locations. Conversations that led with arguments moved nobody. The identical conversations with one addition, a non-judgmental swap of personal stories, cut exclusionary attitudes for at least four months. The persuasive ingredient was never the evidence. It was the absence of contempt.

State the limits plainly. The effects are real but modest. They were measured on policy attitudes, not ballots. And the method is retail: one door, ten minutes, no shortcut and no scale. It is also the only approach in this entire field that keeps replicating, which is more than anyone can say for the quote-tweet.

What this means by November

New Hampshire votes in fifteen weeks, with an open U.S. Senate seat, both congressional districts, and the entire Legislature on the ballot. Both parties will spend millions trying to move a sliver of voters the evidence says cannot be moved by ads calling them fools. Meanwhile the three levers sit in plain sight. Democrats who open with the fact-check are spending money to harden the wall. Republicans watching voters under 30 walk away should read the Yale numbers again: the promise those voters heard was affordability, and every grocery receipt is now the opposition’s ad. And anyone with a MAGA brother-in-law has better tools than a link. Ask him what he voted for. Ask whether he got it. Then stop talking and listen, because that, per the only replicated studies we have, is the part that works. The same rule sits under our recent piece on why Americans hold false beliefs: knowing why someone believes a falsehood is worthless the moment you use it as a club.

Greene said the quiet part on her way out: both parties use ordinary Americans election after election, and life for those Americans never improves. She is not wrong about the mechanism, whatever else she has been wrong about. The MAGA mind changes the way hers did. Not when it loses an argument. It changes when the promise breaks, the bill arrives, and somebody leaves the door open instead of slamming it. New Hampshire tests all three in November.
