Cheryl Sharp, a 47-year-old sales associate who was among the many Iowans turned away from a filled-to-capacity Trump rally last month, sounded pretty confident she knew why Donald Trump was so appealing to many voters. For her and many others, she said, his most important quality was strength: He had the fortitude to keep the country safe, avoid new wars and ensure the economy hummed along.

"You want someone strong, globally, so that it creates mutual respect with other countries, and maybe a little bit of fear," she told me. "Yes, it's true, not everyone likes him. It's good not to be liked. Being strong is better." Sharp readily conceded that not everything Trump said was great, but she saw that as part of the right personality to be president. "You gotta be a little crazy, maybe, to make sure other countries respect and fear us," she said. "And he can run the country like a business, and they will leave him alone."

Three days later, inside a Trump rally in New Hampshire, Scott Bobbitt and his wife, Heather, also brought up Trump's strength. "He commands respect and fear around the world," Scott Bobbitt told me. "Many people may be driven by fear of him because he'll do what he says he's going to do, and he's not afraid to talk about it. And I think that that's very powerful. That does protect our country, and he'll stand up instead of rolling over."

I first began attending Trump rallies eight years ago, to try to better understand a candidate who was then being described as a joke — someone with little to no chance of winning the Republican nomination, let alone the presidency — and came away struck by his mix of charisma and powerful command of audiences.

Rather than the bumbling celebrity I expected, I encountered a politician laying the groundwork for a powerful political realignment around subjects too readily brushed aside by the bipartisan establishment in Washington, such as the loss of manufacturing in the U.S.; those left behind by globalization and trade, especially trade with China; the legacy of the Iraq war and U.S. involvement in foreign wars in general; and, of course, immigration.

I recently started going to Trump rallies and following his supporters' online political conversations once again, to try to better understand something else: his base, and specifically the question of authoritarianism and the American voter.

The authoritarian label has been attached to Trump by critics for years, especially after he sought to overturn the 2020 election results, which culminated in the attack on the U.S. Capitol on Jan. 6, 2021. I have studied and written about authoritarianism for years, and I think it's important to pay attention to the views and motivations of voters who support authoritarian politicians, even when these politicians are seen by many as threats to the democratic order.

My curiosity isn't merely intellectual. Around the world, these politicians are not just getting elected democratically; they are often retaining enough popular support after a term — or two or three — to get re-elected. Polls strongly suggest that Trump has a reasonable chance of winning another term in November. And he has clearly retained his hold on the Republican Party base: His Republican challengers either seem to be angling to be his vice president or are struggling to climb in the polls.

What I wanted to understand was, why? Why Trump? Even if these voters were unhappy with President Joe Biden, why not a less polarizing Republican, one without indictments and all that dictator talk? Why does Trump have so much enduring appeal?

In my talks with more than 100 voters, no one mentioned the word "authoritarian." But that was no surprise — many everyday people don't think in those terms. Focusing solely on these labels can miss the point.

Authoritarian leaders project qualities that many voters — not just Trump voters — admire: strength, a sense of control, even an ends-justify-the-means leadership style. Our movie-hero presidents, "Top Gun" pilots and crusading lawyers often take matters into their own hands or break the rules in ways that we cheer. No, they are not classic authoritarians jailing opponents, but they have something in common with Trump: They are seen as having special or singular strengths, an "I alone can fix it" power.

What I heard from voters drawn to Trump was that he had a special strength in making the economy work better for them than Biden has, and that he was a tough, "don't mess with me" absolutist, which they see as helping to prevent new wars. His supporters also see him as an authentic strongman who is not a typical politician, and Trump sells that message very well to his base.

In New Hampshire, Jackie Fashjian made the case to me that during Trump's presidency, "there weren't any active wars going on except for Afghanistan, which he did not start. He started no new wars. Our economy was great. Our gas prices were under 2 bucks a gallon. It's just common sense to me. If it ain't broke, don't fix it."

At the same rally, Debbie Finch leaped to her feet when Trump walked into the arena, and like many around us, she started filming. Finch defies stereotypes of Trump supporters: She's Black and is concerned with racism, which she says greatly affects her life and that of her children. She doesn't deny there are racists among Trump's supporters, but as far as she's concerned, that goes for Democrats, too. She told me she supports Trump because the economy was better under him. She doesn't care about Trump's indictments; the justice system has been derailing Black men forever, she says, and she predicts more and more minority voters will cast their ballots for him. (Trump does poll higher among minorities than past Republican presidents in the modern era and his current competitors for the nomination.)

Trump's vulgar language, his penchant for insults ("Don't call him a fat pig," he said about Chris Christie) and his rhetoric about political opponents (promising to "root out the communists, Marxists, fascists and the radical left thugs that live like vermin within the confines of our country") are seen as signs of authenticity and strength by his supporters. All the politicians say things like that in private, countless Trump supporters asserted to me and argued that it's just Trump who's strong and honest enough to say it out loud — for them, a sign that he's honest.

Voter after voter told me that they think Biden is too weak and too old to be president. They talk about him with attack lines frequently used by Trump, saying that he's senile, falling down stairs, losing his train of thought while talking and so on. Biden, Trump grimly warned the crowd in Iowa, "can't put two sentences together and he's responsible for negotiations on nuclear weapons in World War III."

Nationally, polls show that voters are more concerned about Biden's age than Trump's. If 2024 comes down to Biden vs. Trump, the politicians will be 81 and 78, respectively, the oldest matchup ever.

Polls also show that voters believe that Trump would do a better job than Biden on the economy, foreign policy and immigration. It was Trump's perceived strength, in contrast with Biden's perceived weakness, that was the common theme that tied it all together for his supporters.

Take foreign policy. Many Trump supporters told me that had Trump been president, the war in Ukraine wouldn't have happened because he would have been strong enough to be feared by Vladimir Putin or smart enough to make a deal with him, if necessary. Neither would Hamas have dared attack Israel, a few added. Their proof was that during Trump's presidency, these wars indeed did not happen. Of course, the more relevant question is whether these wars would have happened during a second Trump term — a counterfactual that can't be proved or disproved.

Projecting strength and being seen as authentic are common themes among other leaders whom political scientists would call "competitive authoritarians." In their regimes, many of the basic tenets of liberal democracy are violated, but elections, largely free of widespread fraud, are regularly held. Many political scientists place Narendra Modi of India (his party recently won major victories in state elections, and a third term is possible), Recep Tayyip Erdogan of Turkey (on his third term as president, after three stints as prime minister) and Viktor Orban of Hungary (in his fourth consecutive term) in this category.

Like many of these right-wing populists, Trump leans heavily on the message that he alone is strong enough to keep America peaceful and prosperous in a scary world. Right after his recent landslide reelection, Orban said his party had won despite everyone being against them, and now he would ensure that Hungary would be "strong, rich and green." In Iowa, Trump praised Orban himself before telling a cheering crowd: "For four straight years, I kept America safe. I kept Israel safe. I kept Ukraine safe, and I kept the entire world safe."

As he spoke such words at various rallies, the crowds often interrupted him with applause and cheering. From another politician, such claims might have sounded so implausibly grandiose as to fall flat. But from Trump, these statements often resulted in the crowds leaping to their feet (actually, some rallygoers never sat down) and interrupting him with applause and cheering.

That's charisma. Charisma is an underrated aspect of political success — and it's not necessarily a function of political viewpoint. Bill Clinton and Barack Obama oozed it, for example, and so does Trump.

Charisma is so central to politics that Max Weber, a founder of sociology, included charismatic authority (along with legal authority, as in republics and democracies; and traditional authority, as in feudalism or monarchy) as one of three types of power people see as legitimate. Charismatic leaders, Weber wrote, "have a certain quality of an individual personality, by virtue of which he is set apart from ordinary men," and is sought as a leader, especially when people feel the times are troubled.

So what about democracy, then? I pressed many Trump supporters about the events around Jan. 6, 2021, at the Capitol. I didn't encounter a single outright supporter of what happened, but many people explained the events away. Increasingly separate information environments and our fractured media ecology shape the way people view that day.

Some Trump supporters told me that whatever happened was carried out by a fringe faction that did not represent Trump's base. Didn't some Black Lives Matter protesters get carried away and even damage small businesses owned by Black people?, Jackie Fashjian said to me. Debbie Finch asked me whether Kamala Harris should be responsible for everything bad done during Black Lives Matter protests.

Many also didn't trust the government or traditional media's telling of what happened on Jan. 6. "I'm not concerned with Jan. 6," Finch said. "I don't trust our government. I don't trust anything they're saying. They've been doing this to Black people for so long, railroading them, so they have zero credibility. So I don't even care about it, and I don't want to hear about Jan. 6."

Others, like Hunter Larkner, a young man who said he was a great fan of Elon Musk and used Twitter and YouTube for doing his research, said he was shocked when he first heard about the events of Jan. 6. But as he looked into it, he decided it must have been entrapment — that authorities deliberately allowed the rampage in the Capitol to happen.

Cheryl Sharp told me that she doesn't worry about all the talk of Trump being a dictator. For her, biased mainstream media is misrepresenting him. "He was making the point that he'd use executive orders on Day 1, like the others do — executive orders bypass Congress, but that's how it's done these days," she said. "He was being sarcastic, not saying he'd be a real dictator."

It's easy to see why Trump's political message can override concerns about the process of democracy for many. What's a bit of due process overstepped here, a trampled emoluments clause there, when all politicians are believed to be corrupt and fractured information sources pump very different messages about reality?

Politicians projecting strength at the expense of the rules of liberal democracy isn't a new phenomenon in the United States, or the world. Thomas Jefferson worried about it. So did Plato. Perhaps acknowledging that Trump's appeal isn't that mysterious can help people grapple with its power.
