Ezra Klein explains on vox.com.

It is undeniably enjoyable watching Trump. He’s red-faced, discursive, funny, angry, strange, unpredictable, and real. He speaks without filter and tweets with reckless abandon. The Donald Trump phenomenon is a riotous union of candidate ego and voter id. America’s most skilled political entertainer is putting on the greatest show we’ve ever seen.

It’s so fun to watch that it’s easy to lose sight of how terrifying it really is.

Trump is the most dangerous major candidate for president in memory. He pairs terrible ideas with an alarming temperament; he’s a racist, a sexist, and a demagogue, but he’s also a narcissist, a bully, and a dilettante. He lies so constantly and so fluently that it’s hard to know if he even realizes he’s lying. He delights in schoolyard taunts and luxuriates in backlash.

Behind Trump’s success is an unerring instinct for harnessing anger, resentment, and fear. His view of the economy is entirely zero-sum — for Americans to win, others must lose. “We’re going to make America great again,” he said in his New Hampshire victory speech, “but we’re going to do it the old fashioned way. We’re going to beat China, Japan, beat Mexico at trade. We’re going to beat all of these countries that are taking so much of our money away from us on a daily basis. It’s not going to happen anymore.”

Trump answers America’s rage with more rage. As the journalist Molly Ball observed, “All the other candidates say ‘Americans are angry, and I understand.’ Trump says, ‘I’M angry.'” Trump doesn’t offer solutions so much as he offers villains. His message isn’t so much that he’ll help you as he’ll hurt them.

Trump’s other gift — the one that gets less attention, but is perhaps more important — is his complete lack of shame. It’s easy to underestimate how important shame is in American politics. But shame is our most powerful restraint on politicians who would find success through demagoguery. Most people feel shame when they’re exposed as liars, when they’re seen as uninformed, when their behavior is thought cruel, when respected figures in their party condemn their actions, when experts dismiss their proposals, when they are mocked and booed and protested.

Trump doesn’t. He has the reality television star’s ability to operate entirely without shame, and that permits him to operate entirely without restraint. It is the single scariest facet of his personality. It is the one that allows him to go where others won’t, to say what others can’t, to do what others wouldn’t.

Trump lives by the reality-television trope that he’s not here to make friends. But the reason reality-television villains always say they’re not there to make friends is because it sets them apart, makes them unpredictable and fun to watch. “I’m not here to make friends” is another way of saying “I’m not bound by the social conventions of normal people.” The rest of us are here to make friends, and it makes us boring, gentle, kind.

This, more than his ideology, is why Trump genuinely scares me. There are places where I think Trump’s instincts are an improvement on the Republican field. He seems more dovish than neoconservatives like Marco Rubio, and less dismissive of the social safety net than libertarians like Rand Paul. But those candidates are checked by institutions and incentives that hold no sway over Trump; his temperament is so immature, his narcissism so clear, his political base so unique, his reactions so strange, that I honestly have no idea what he would do — or what he wouldn’t do.
