On Saturday, someone tried to kill Donald Trump.
You may not have heard about it. The story didn't get much play, the attempt wasn't well planned and the candidate was never in jeopardy.
Still the fact remains that authorities arrested one Michael Steven Sandford, 19, after he allegedly tried to grab a gun from the holster of a Las Vegas police officer with the idea of using it to kill Trump at a campaign rally. Authorities say Sandford, who carried a UK driver's license but who had been living in New Jersey for about a year and a half, had visited a nearby gun range to learn how to handle a firearm. They say he has wanted to kill Trump for a year.
Let us be thankful he was not successful. The assassination of Donald Trump would have been a new low for a political season that is already the most dispiriting in memory. It would have deprived a family of its father and husband. It would have traumatized a nation where political murder has been a too-frequent tragedy.
And it would have imparted the moral authority of martyrdom to Trump's ideas. That would be a disaster in its own right.
Like most would-be assassins, what Sandford apparently did not understand is that you cannot kill an idea with a bullet. Even bad ideas are impervious to gunfire.
Trump, of course, has been a veritable Vesuvius of bad ideas in the year since he took that escalator ride into the race for the presidency. From banning Muslim immigrants to building a wall on the southern border to punishing women who have abortions to advocating guns in nightclubs to judging judicial fitness based on heritage, to killing the wives and children of terror suspects, if there has been a hideous, unserious or flat-out stupid thought floated in this political season, odds are, it carried the Trump logo.
It is understandable, then, that even people who wish Trump no bodily harm might feel as Sandford presumably did: that if he were somehow just ... gone, the stench of his ideas -- of his anger, nativism, coarseness and proud ignorance -- might somehow waft away like trash-fire smoke in a breeze.
But it doesn't work that way. Martin Luther King's dream of racial equality did not die on the balcony of the Lorraine Motel. Nor did Adolf Hitler's dream of racial extermination perish with him in that bunker beneath Berlin. Ideas, both transcendent and repugnant, are far hardier than the fragile lives of the men and women who give them voice.
So, any hope that Trump's disappearance would somehow fix America is naive. America's problem has nothing to do with him, except to the degree he has made himself a focal point.
No, America's problem is fear. Fear of economic stagnation, yes, and fear of terrorism. But those are proxies for the bigger and more fundamental fear: fear of demographic diminution, of losing the privileges and prerogatives that have always come with being straight, white, male and/or Christian in America. It was the holy quadfecta of entitlement, but that entitlement is under siege in a nation that grows more sexually, racially and religiously diverse with every sunrise.
Trumpism is only the loudest and most obvious response to that, and it will not disappear when he does. Indeed, there is no instant cure for what has America unsettled. There is only time and the hard work of change.
In a sense, we are bringing forth a new nation, conceived in liberty and dedicated to the proposition that all men and women really are created equal. If for some of us, that fires the imagination, it is hardly mysterious that for others, it kindles a sense of displacement and loss. The good news is that their Trumpism cannot survive in the new nation.
In the end, you see, only one thing can kill a bad idea.
And that's a better one.
