Long before Donald Trump declared he would run for president, his first political adviser articulated the central idea that has come to define both candidate and campaign.

"Hate is a stronger motivator than love," said Roger Stone in 2008 — and that corrosive outlook is obviously what still drives the Watergate-vintage dirty trickster and pardoned felon (although he now claims to be a born-again "Christian"). It is also what drives the man whose political persona Stone created.

The Trump campaign, and the MAGA movement at its core, embodies a malevolent spirit of hostility that endangers democracy, domestic tranquility and the very future of the nation. Both the candidate and his surrogates persistently spew out a noxious fog of deception and demonization, aimed at dehumanizing vulnerable populations that cannot fight back.

Sounding like a dollar-store knockoff of Hitler, Trump keeps intensifying his racist rants against migrants and minorities he describes as genetically inferior and predisposed to criminal conduct, from eating other people's pets to slitting the throats of young women. He has commenced a tour of cities supposedly overrun by these dark-skinned marauders, even as the local Republican officials have begged him to desist from his absurd lies and violent instigation.

But almost as toxic, and perhaps even more bizarre, is the Trump campaign's lurid, clamorous barrage of advertising aimed at trans people. So far, the Republicans and their allies have spent roughly $30 million on ads that aim to conflate trans people with murderers — and persuading them that Democratic nominee Kamala Harris is devoted to advancing the interests of those trans killers above all else. While it is true that Harris has supported gender-affirming health care, including for prisoners, it is also true that the federal prison system under Trump provided that same care — as the law requires.

But what is so weird — how else to put it? — about the Trump anti-trans crusade is its hidden underwriter. Behind the spending on much of the MAGA hate propaganda, especially the messages dehumanizing trans people, is none other than billionaire troll Elon Musk. Hatred is a more powerful motivator than love for a twisted character like Musk too, even when the object of that revulsion is his own child.

Now Musk, a pompous proponent of "conservative family values," has often bragged about littering the world with his offspring, possibly too many to identify. But what we know for certain is that he has a trans daughter who has changed her name to Vivian Wilson and successfully petitioned the courts to dissociate herself from her cruel father.

Rarely present for Vivian when she was growing up, Musk has gone so far as to proclaim that his erstwhile son is "dead, killed by the woke mind virus," and mock his child publicly for being "gay and slightly autistic" from an early age. Vivian says Musk knows nothing about her and has lied about being "tricked" into approving the medical treatment she insists saved her life.

It is worth noting here that this same notorious troll, who has reportedly financed millions of dollars' worth of anti-immigrant vitriol online and on the airwaves, is himself a migrant from South Africa via Canada — and has collected more money from government, both state and federal, than any 10 million working-class noncitizens. His reintroduction of Nazism, white supremacy and outrageous conspiracies and falsehoods on his social media platform X makes him a far greater menace to American communities than those who have crossed the southern border to escape violence and seek a better life for their kids. Before the mass deportation begins, perhaps we could have a more selective approach.

Ugliness and grievance suffuse the Trump movement. They are as visible as a pustulent sore, not only in the would-be president's threatening rhetoric but in the aggressive thrust of his backers. Trump's social poison protrudes in different directions, always exposing the internalized fury of those around him, from his adviser Stephen Miller's desire to destroy immigrant families, to JD Vance's undisguised anger at the women who remind him of his errant mother, to Musk's festering grudge against his daughter.

An American political campaign, especially for the presidency, would normally seek to promote a vision of the future, an inspiring call to patriotism, or even a platform of policies and proposals. What Trump and his coterie of billionaires offer instead is incitement and the prospect of bloodshed, all so they can profit and loot the Treasury at will. What they are delivering already is a hellscape of hatred — just as Stone so gleefully warned us.
